+ * @brief    Database discovery module.
+ *
+ * @details  This module contains the APIs and types exposed by the DB Discovery module. These APIs
+ *           and types can be used by the application to perform discovery of a service and its
+ *           characteristics at the peer server. This module can also be used to discover the
+ *           desired services in multiple remote devices.
+ *
+ * @warning  The maximum number of characteristics per service that can be discovered by this module
+ *           is determined by the number of characteristics in the service structure defined in
+ *           db_disc_config.h. If the peer has more than the supported number of characteristics, then
+ *           the first found will be discovered and any further characteristics will be ignored. Only the
+ *           following descriptors will be searched for at the peer: Client Characteristic Configuration,
+ *           Characteristic Extended Properties, Characteristic User Description, and Report Reference.
+ *
+ * @note     Presently only one instance of a Primary Service can be discovered by this module. If
+ *           there are multiple instances of the service at the peer, only the first instance
+ *           of it at the peer is fetched and returned to the application.
+ *
+ * @note     The application must propagate BLE stack events to this module by calling
+ *           ble_db_discovery_on_ble_evt().

+ *
+ * @brief Apple Notification Center Service Client Module.
+ *
+ * @details Disclaimer: This client implementation of the Apple Notification Center Service can
+ *          be changed at any time by Nordic Semiconductor ASA. Server implementations such as the
+ *          ones found in iOS can be changed at any time by Apple and may cause this client
+ *          implementation to stop working.
+ *
+ * This module implements the Apple Notification Center Service (ANCS) client.
+ * This client can be used as a Notification Consumer (NC) that receives data
+ * notifications from a Notification Provider (NP). The NP is typically an iOS
+ * device acting as a server. For terminology and up-to-date specs, see
+ * http://developer.apple.com.
+ *
+ * The term "notification" is used in two different meanings:
+ * - An <i>iOS notification</i> is the data received from the Notification Provider.
+ * - A <i>GATTC notification</i> is a way to transfer data with <i>Bluetooth</i> Smart.
+ * In this module, we receive iOS notifications using GATTC notifications.
+ * We use the full term (iOS notification or GATTC notification) where required to avoid confusion.
+ *
+ * Upon initializing the module, you must add the different iOS notification attributes you
+ * would like to receive for iOS notifications (see @ref nrf_ble_ancs_c_attr_add).
+ *
+ * Once a connection is established with a central device, the module does a service discovery to
+ * discover the ANCS server handles. If this succeeds (@ref BLE_ANCS_C_EVT_DISCOVERY_COMPLETE),
+ * the handles for the ANCS server are part of the @ref ble_ancs_c_evt_t structure and must be
+ * assigned to an ANCS_C instance using the @ref nrf_ble_ancs_c_handles_assign function. For more
+ * information about service discovery, see the @ref lib_ble_db_discovery documentation.
+ *
+ * The application can now subscribe to iOS notifications using
+ * @ref ble_ancs_c_notif_source_notif_enable. They arrive in the @ref BLE_ANCS_C_EVT_NOTIF event.
+ * @ref nrf_ble_ancs_c_request_attrs can be used to request attributes for the notifications. They
+ * arrive in the @ref BLE_ANCS_C_EVT_NOTIF_ATTRIBUTE event.
+ * @ref nrf_ble_ancs_c_app_attr_request can be used to request attributes of the app that issued
+ * the notifications. They arrive in the @ref BLE_ANCS_C_EVT_APP_ATTRIBUTE event.
+ * @ref nrf_ancs_perform_notif_action can be used to make the Notification Provider perform an
+ * action based on the provided notification.

+ *
+ * @details This module implements the Battery Service with the Battery Level characteristic.
+ *          During initialization it adds the Battery Service and Battery Level characteristic
+ *          to the BLE stack database. Optionally it can also add a Report Reference descriptor
+ *          to the Battery Level characteristic (used when including the Battery Service in
+ *          the HID service).
+ *
+ *          If specified, the module will support notification of the Battery Level characteristic
+ *          through the ble_bas_battery_level_update() function.
+ *          If an event handler is supplied by the application, the Battery Service will
+ *          generate Battery Service events to the application.
+ *
+ * @note    The application must register this module as BLE event observer using the
+ *          NRF_SDH_BLE_OBSERVER macro. Example:
+ *          @code
+ *              ble_bas_t instance;

+ * @brief Cycling Speed and Cadence Service module.
+ *
+ * @details This module implements the Cycling Speed and Cadence Service. If enabled, notification
+ *          of the Cycling Speead and Candence Measurement is performed when the application
+ *          calls ble_cscs_measurement_send().
+ *
+ *          To use this service, you need to provide the the supported features (@ref BLE_CSCS_FEATURES).
+ *          If you choose to support Wheel revolution data (feature bit @ref BLE_CSCS_FEATURE_WHEEL_REV_BIT),
+ *          you then need to support the 'setting of cumulative value' operation by the supporting the
+ *          Speed and Cadence Control Point (@ref ble_sdk_srv_sc_ctrlpt) by setting the @ref BLE_SRV_SC_CTRLPT_CUM_VAL_OP_SUPPORTED
+ *          bit of the ctrplt_supported_functions in the @ref ble_cscs_init_t structure.
+ *          If you want to support the 'start autocalibration' control point feature, you need, after the @ref BLE_SC_CTRLPT_EVT_START_CALIBRATION
+ *          has been received and the auto calibration is finished, to call the @ref ble_sc_ctrlpt_rsp_send to indicate that the operation is finished
+ *          and thus be able to receive new control point operations.
+ *          If you want to support the 'sensor location' related operation, you need to provide a list of supported location in the
+ *          @ref ble_cscs_init_t structure.
+ *
+ *
+ * @note    The application must register this module as BLE event observer using the
+ *          NRF_SDH_BLE_OBSERVER macro. Example:
+ *          @code
+ *              ble_cscs_t instance;
+ *              NRF_SDH_BLE_OBSERVER(anything, BLE_CSCS_BLE_OBSERVER_PRIO,
+ *                                   ble_cscs_on_ble_evt, &instance);
+ *          @endcode
+ *
+ * @note Attention!
+ *  To maintain compliance with Nordic Semiconductor ASA Bluetooth profile
+ *  qualification listings, this section of source code must not be modified.

+ * @brief Current Time Service client module.
+ *
+ * @details This module implements the Current Time Service (CTS) client-peripheral role of
+ *          the Time Profile. After security is established, the module tries to discover the
+ *          Current Time Service and Characteristic on the central side. If this succeeds,
+ *          the application can trigger a read of the current time from the connected server.
+ *
+ *          The module informs the application about a successful discovery using the
+ *          @ref BLE_CTS_C_EVT_DISCOVERY_COMPLETE event. The handles for the CTS server is now
+ *          available in the @ref ble_cts_c_evt_t structure. These handles must be assigned to an
+ *          instance of CTS_C, using @ref ble_cts_c_handles_assign. For more information about
+ *          service discovery, see the ble_discovery module documentation @ref lib_ble_db_discovery.
+ *
+ *          The application can then use the function @ref ble_cts_c_current_time_read to read the
+ *          current time. If the read succeeds, it will trigger either a
+ *          @ref BLE_CTS_C_EVT_CURRENT_TIME event or a @ref BLE_CTS_C_EVT_INVALID_TIME event
+ *          (depending on if the data that was read was actually a valid time), which is then sent
+ *          to the application. The current time is then available in the params field of the
+ *          passed @ref ble_cts_c_evt_t structure.
+ *
+ * @note    The application must register this module as BLE event observer using the
+ *          NRF_SDH_BLE_OBSERVER macro. Example:
+ *          @code
+ *              ble_cts_c_t instance;
+ *              NRF_SDH_BLE_OBSERVER(anything, BLE_CTS_C_BLE_OBSERVER_PRIO,
+ *                                   ble_cts_c_on_ble_evt, &instance);

+ *
+ * @details This module implements the Human Interface Device Service with the corresponding set of
+ *          characteristics. During initialization it adds the Human Interface Device Service and
+ *          a set of characteristics as per the Human Interface Device Service specification and
+ *          the user requirements to the BLE stack database.
+ *
+ *          If enabled, notification of Input Report characteristics is performed when the
+ *          application calls the corresponding ble_hids_xx_input_report_send() function.
+ *
+ *          If an event handler is supplied by the application, the Human Interface Device Service
+ *          will generate Human Interface Device Service events to the application.
+ *
+ * @note    The application must register this module as BLE event observer using the
+ *          NRF_SDH_BLE_OBSERVER macro. Example:
+ *          @code
+ *              ble_hids_t instance;
+ *              NRF_SDH_BLE_OBSERVER(anything, BLE_HIDS_BLE_OBSERVER_PRIO,
+ *                                   ble_hids_on_ble_evt, &instance);
+ *          @endcode
+ *
+ * @note Attention!
+ *  To maintain compliance with Nordic Semiconductor ASA Bluetooth profile
+ *  qualification listings, this section of source code must not be modified.

+ * @brief Heart Rate Service module.
+ *
+ * @details This module implements the Heart Rate Service with the Heart Rate Measurement,
+ *          Body Sensor Location and Heart Rate Control Point characteristics.
+ *          During initialization it adds the Heart Rate Service and Heart Rate Measurement
+ *          characteristic to the BLE stack database. Optionally it also adds the
+ *          Body Sensor Location and Heart Rate Control Point characteristics.
+ *
+ *          If enabled, notification of the Heart Rate Measurement characteristic is performed
+ *          when the application calls ble_hrs_heart_rate_measurement_send().
+ *
+ *          The Heart Rate Service also provides a set of functions for manipulating the
+ *          various fields in the Heart Rate Measurement characteristic, as well as setting
+ *          the Body Sensor Location characteristic value.
+ *
+ *          If an event handler is supplied by the application, the Heart Rate Service will
+ *          generate Heart Rate Service events to the application.
+ *
+ * @note    The application must register this module as BLE event observer using the
+ *          NRF_SDH_BLE_OBSERVER macro. Example:
+ *          @code
+ *              ble_hrs_t instance;
+ *              NRF_SDH_BLE_OBSERVER(anything, BLE_HRS_BLE_OBSERVER_PRIO,
+ *                                   ble_hrs_on_ble_evt, &instance);
+ *          @endcode
+ *
+ * @note Attention!
+ *  To maintain compliance with Nordic Semiconductor ASA Bluetooth profile
+ *  qualification listings, this section of source code must not be modified.

+ * @brief    Heart Rate Service Client module.
+ *
+ * @details  This module contains the APIs and types exposed by the Heart Rate Service Client
+ *           module. These APIs and types can be used by the application to perform discovery of
+ *           Heart Rate Service at the peer and interact with it.
+ *
+ * @warning  Currently this module only has support for Heart Rate Measurement characteristic. This
+ *           means that it will be able to enable notification of the characteristic at the peer and
+ *           be able to receive Heart Rate Measurement notifications from the peer. It does not
+ *           support the Body Sensor Location and the Heart Rate Control Point characteristics.
+ *           When a Heart Rate Measurement is received, this module will decode only the
+ *           Heart Rate Measurement Value (both 8 bit and 16 bit) field from it and provide it to
+ *           the application.
+ *
+ * @note    The application must register this module as BLE event observer using the
+ *          NRF_SDH_BLE_OBSERVER macro. Example:
+ *          @code
+ *              ble_hrs_c_t instance;
+ *              NRF_SDH_BLE_OBSERVER(anything, BLE_HRS_C_BLE_OBSERVER_PRIO,
+ *                                   ble_hrs_c_on_ble_evt, &instance);

+ * @details This module implements the Immediate Alert Service with the Alert Level characteristic.
+ *          During initialization it adds the Immediate Alert Service and Alert Level characteristic
+ *          to the BLE stack database.
+ *
+ *          The application must supply an event handler for receiving Immediate Alert Service
+ *          events. Using this handler, the service will notify the application when the
+ *          Alert Level characteristic value changes.
+ *
+ *          The service also provides a function for letting the application poll the current
+ *          value of the Alert Level characteristic.
+ *
+ * @note    The application must register this module as BLE event observer using the
+ *          NRF_SDH_BLE_OBSERVER macro. Example:
+ *          @code
+ *              ble_ias_t instance;

+ * @brief LED Button Service Server module.
+ *
+ * @details This module implements a custom LED Button Service with an LED and Button Characteristics.
+ *          During initialization, the module adds the LED Button Service and Characteristics
+ *          to the BLE stack database.
+ *
+ *          The application must supply an event handler for receiving LED Button Service
+ *          events. Using this handler, the service notifies the application when the
+ *          LED value changes.
+ *
+ *          The service also provides a function for letting the application notify
+ *          the state of the Button Characteristic to connected peers.
+ *
+ * @note    The application must register this module as BLE event observer using the
+ *          NRF_SDH_BLE_OBSERVER macro. Example:
+ *          @code
+ *              ble_hids_t instance;
+ *              NRF_SDH_BLE_OBSERVER(anything, BLE_HIDS_BLE_OBSERVER_PRIO,

+ * @details This module implements the Link Loss Service with the Alert Level characteristic.
+ *          During initialization it adds the Link Loss Service and Alert Level characteristic
+ *          to the BLE stack database.
+ *
+ *          The application must supply an event handler for receiving Link Loss Service
+ *          events. Using this handler, the service will notify the application when the
+ *          link has been lost, and which Alert Level has been set.
+ *
+ *          The service also provides a function for letting the application poll the current
+ *          value of the Alert Level characteristic.
+ *
+ * @note    The application must register this module as BLE event observer using the
+ *          NRF_SDH_BLE_OBSERVER macro. Example:
+ *          @code
+ *              ble_lls_t instance;

+ * @brief    Nordic UART Service implementation.
+ *
+ * @details The Nordic UART Service is a simple GATT-based service with TX and RX characteristics.
+ *          Data received from the peer is passed to the application, and the data received
+ *          from the application of this service is sent to the peer as Handle Value
+ *          Notifications. This module demonstrates how to implement a custom GATT-based
+ *          service and characteristics using the SoftDevice. The service
+ *          is used by the application to send and receive ASCII text strings to and from the
+ *          peer.
+ *
+ * @note    The application must register this module as BLE event observer using the
+ *          NRF_SDH_BLE_OBSERVER macro. Example:
+ *          @code
+ *              ble_nus_t instance;
+ *              NRF_SDH_BLE_OBSERVER(anything, BLE_NUS_BLE_OBSERVER_PRIO,
+ *                                   ble_nus_on_ble_evt, &instance);

+ * @details This module implements the Running Speed and Cadence Service. If enabled, notification
+ *          of the Running Speead and Candence Measurement is performed when the application
+ *          calls ble_rscs_measurement_send().
+ *
+ *          If an event handler is supplied by the application, the Running Speed and Cadence
+ *          Service will generate Running Speed and Cadence Service events to the application.
+ *
+ * @note    The application must register this module as BLE event observer using the
+ *          NRF_SDH_BLE_OBSERVER macro. Example:
+ *          @code
+ *              ble_rscs_t instance;
+ *              NRF_SDH_BLE_OBSERVER(anything, BLE_RSCS_BLE_OBSERVER_PRIO,
+ *                                   ble_rscs_on_ble_evt, &instance);
+ *          @endcode
+ *
+ * @note Attention!
+ *  To maintain compliance with Nordic Semiconductor ASA Bluetooth profile
+ *  qualification listings, this section of source code must not be modified.

+ * @brief Continuous Glucose Monitoring Service (CGMS) module.
+ *
+ * @details This module implements a sensor for the Continuous Glucose Monitoring Service.
+ *          The sensor is a GATT Server that sends CGM measurements to a connected CGMS
+ *          Collector. The CGMS Sensor stores records that can be accessed with the
+ *          Record Access Control Point (RACP). The collector can access the features and status
+ *          of the sensor. Session Run Time and Session Start Time can be used to convey timing
+ *          information between the sensor and the collector. The Specific Operations Control Point
+ *          is used to stop and start monitoring sessions, among other things.
+ *
+ * @note    The application must register this module as BLE event observer using the
+ *          NRF_SDH_BLE_OBSERVER macro. Example:
+ *          @code
+ *              nrf_ble_cgms_t instance;
+ *              NRF_SDH_BLE_OBSERVER(anything, NRF_BLE_CGMS_BLE_OBSERVER_PRIO,
+ *                                   nrf_ble_cgms_on_ble_evt, &instance);

+ * @details This module implements the Bond Management Service (BMS).
+ *          By writing to the Bond Management Control Point, the connected peer can request the deletion of
+ *          bond information from the device.
+ *          If authorization is configured, the application must supply an event handler for receiving Bond
+ *          Management Service events. Using this handler, the service requests authorization when
+ *          a procedure is requested by writing to the Bond Management Control Point.

+/**
+ * @brief Sensor driver usage.
+ *
+ * Sensor instance has to be defined first in global context using @ref LPS22HB_INSTANCE DEF.
+ * After that it has to be initialized using @ref lps22hb_init.
+ * At this point sensor instance is ready and all other functions can be used.
+ *
+ * There are two ways in which sensor settings are set:
+ *
+ * First one are asynchronous macros, using them does not change real sensor settings
+ * until @ref lps22hb_cfg_commit is called.
+ * Example:
+ * LPS22HB_DATA_CFG(m_sensor1, LPS22HB_ODR_POWERDOWN, false, false);
+ * LPS22HB_FIFO_CFG(m_sensor1, LPS22HB_STREAM, true, false, 15);
+ * lps22hb_cfg_commit(&m_sensor1);
+ *
+ * Second way are functions, functions schedule TWI operation using @ref nrf_twi_sensor module.
+ * After calling function, setting will be automatically send to sensor when TWI bus is free.
+ * Example:
+ * lps22hb_low_power_enable(&m_sensor1, true);
+ * lps22hb_offset_set(&m_sensor1, -27);
+ *
+ * There are designated functions to read status sensor registers e.g. @ref lps22hb_int_source_read
+ * As parameters they receive function to be called after register is read, and pointer where
+ * register value should be stored. From that value specific parameters can be extracted
+ * using @ref NRF_TWI_SENSOR_REG_VAL_GET macro.
+ * Example:
+ * uint8_t ia = NRF_TWI_SENSOR_REG_VAL_GET(int_source_reg, LPS22HB_IA_MASK, LPS22HB_IA_POS);
+ *
+ * Other functions are self-explanatory or have description on their usage.

+ * @brief Error codes for the nRF5x IoT SDK.
+ *
+ * @details
+ * Error codes are 32-bit unsigned integers. The most significant 16 bits (MSB) are reserved for
+ *          identifying the module where the error occurred. The least significant 16 bits (LSB)
+ *          are used to provide the cause or nature of error. Each module is assigned a 16-bit
+ *          unsigned integer, which it will use to identify all errors that occurred in the module.
+ *          For example, if 0x8800 identifies a certain SDK module, all error codes from
+ *          0x88000000 to 0x8800FFFF are reserved for this module.
+ *
+ *          Note that common error reasons have been assigned values to make it
+ *          possible to decode error reasons easily. As an example, if a module is not initialized,
+ *          this error is assigned the error code 0x000A0. If an application encounters an error code
+ *          0xZZZZ00A0, the application knows that it tried to access a certain module without
+ *          initializing it.
+ *
+ *          Each module can define error codes that are not covered by
+ *          the common codes. These values must be defined in a range that does not conflict
+ *          with the common error values. Such module-specific error values might be used by
+ *          different modules to indicate errors of very different nature; so the same error code LSB
+ *          does not necessarily indicate the same error. If an error is already defined by the NRF
+ *          common error codes, however, these codes are reused.
+ *
+ *          A specific range is also reserved for the application. The application can use this range
+ *          to define application-specific errors.
+ *
+ *          The success code NRF_SUCCESS does not include a module identifier.

+ *          The Context Manager contains tables of context, which can be accessed through API functions.

+ *          compress and decompress packets.
+ *
+ *          You can configure the module by changing the @c sdk_config.h configuration file.

+# Socket module
+
+The socket module contains the BSD socket implementation for the IoT SDK. The purpose of the socket
+API is to
+
+* Provide a common API for all platforms
+* Simplify porting of pc network applications
+
+The socket API hides details of the underlying transport, but supports proprietary extensions for
+controlling configuration settings and using underlying transport layers.
+
+<pre>
+socket/
+    api/            - Public socket API headers
+    common/         - Common implementation of API and implementation code shared by all platforms (main socket API implementation, with hooks for different transports)
+    libraries/      - Generic libraries that are not tied to a specific platform
+        portdb/     - Port database to track and allocate socket ports
+        addr_util/  - Common address utilities
+        mbuf/       - Memory buffer utilities
+    transport/      - Transport/network stack hooks
+        ipv6/       - Nordic IPv6 stack transport hook
+        lwip/       - LwIP transport hook
+        test/       - Integration tests shared between transport stacks
+    platform/       - Platform specific code
+        ble/        - BLE specific code (only wrappers around sd_ble_app_evt_())
+    config/         - Configuration socket implementations
+        medium/     - Medium configuration socket implementation

+ * if (NRF_SUCCESS != nrf_atfifo_simple_put(my_fifo, &data, NULL))
+ * {

+ * struct point3d
+ * {
+ *      int x, y, z;
+ * }point3d_t;
+ * nrf_atfifo_context_t context;
+ * point3d_t * point;
+ *
+ * if (NULL != (point = nrf_atfifo_item_alloc(my_fifo, &context)))

+ *      }
+ * }
+ * else
+ * {
+ *      // Error handling
+ * }
+ *
+ * @endcode
+ * @note
+ * This atomic FIFO implementation requires that the operation that is
+ * opened last is finished (committed/flushed) first.
+ * This is typical for operations performed from the interrupt runtime
+ * when the other operation is performed from the main thread.
+ *
+ * This implementation does not support typical multithreading operating system
+ * access where operations can be started and finished in totally unrelated order.

+ *
+ * @brief Buttons handling module.
+ *
+ * @details The button handler uses the @ref app_gpiote to detect that a button has been
+ *          pushed. To handle debouncing, it will start a timer in the GPIOTE event handler.
+ *          The button will only be reported as pushed if the corresponding pin is still active when
+ *          the timer expires. If there is a new GPIOTE event while the timer is running, the timer
+ *          is restarted.
+ *
+ * @note    The app_button module uses the app_timer module. The user must ensure that the queue in
+ *          app_timer is large enough to hold the app_timer_stop() / app_timer_start() operations
+ *          which will be executed on each event from GPIOTE module (2 operations), as well as other
+ *          app_timer operations queued simultaneously in the application.
+ *
+ * @note    Even if the scheduler is not used, app_button.h will include app_scheduler.h, so when
+ *          compiling, app_scheduler.h must be available in one of the compiler include paths.

+ *              - nRF HW RNG peripheral.
+ *                * CTR-DRBG mode - nRF HW RNG used for seeding mbed TLS CTR-DRBG (default for
+ *                  devices without CC310).
+ *                * Raw mode - all data is generated by the nRF HW RNG.
+ *
+ *          The CC310 backend meets the standards NIST 800-90B3 and AIS-31 (Class “P2 High�), and
+ *          should be preferred in most cases on devices that includes the CC310 core. Devices that
+ *          do not include CC310 should normally use the nRF HW RNG with mbed TLS CTR-DRBG. The
+ *          mbed TLS CTR-DRBG code is standardized by NIST (SP 800-90A Rev. 1).

+/**
+ * Set of macros for encoding and decoding header for log entries.
+ * There are 3 types of entries:
+ * 1. Standard entry (STD)
+ *    An entry consists of header, pointer to string and values. Header contains
+ *    severity leveland determines number of arguments and thus size of the entry.
+ *    Since flash address space starts from 0x00000000 and is limited to kB rather
+ *    than MB 22 bits are used to store the address (4MB). It is used that way to
+ *    save one RAM memory.
+ *
+ *    --------------------------------
+ *    |TYPE|SEVERITY|NARGS|    P_STR |
+ *    |------------------------------|
+ *    |    Module_ID (optional)      |
+ *    |------------------------------|
+ *    |    TIMESTAMP (optional)      |
+ *    |------------------------------|
+ *    |             ARG0             |
+ *    |------------------------------|
+ *    |             ....             |
+ *    |------------------------------|
+ *    |             ARG(nargs-1)     |
+ *    --------------------------------
+ *
+ * 2. Hexdump entry (HEXDUMP) is used for dumping raw data. An entry consists of
+ *    header, optional timestamp, pointer to string and data. A header contains
+ *    length (10bit) and offset which is updated after backend processes part of
+ *    data.
+ *
+ *    --------------------------------
+ *    |TYPE|SEVERITY|NARGS|OFFSET|LEN|
+ *    |------------------------------|
+ *    |    Module_ID (optional)      |
+ *    |------------------------------|
+ *    |    TIMESTAMP (optional)      |
+ *    |------------------------------|
+ *    |           P_STR              |
+ *    |------------------------------|
+ *    |             data             |
+ *    |------------------------------|
+ *    |  data |       dummy          |
+ *    --------------------------------
+ *
+ * 3. Pushed string. If string is pushed into the logger internal buffer it is
+ *    stored as PUSHED entry. It consists of header, unused data (optional) and
+ *    string. Unused data is present if string does not not fit into a buffer
+ *    without wrapping (and string cannot be wrapped). In that case header
+ *    contains information about offset.
+ *
+ *    --------------------------------
+ *    |TYPE| OFFSET   |      LEN     |
+ *    |------------------------------|
+ *    |           OFFSET             |
+ *    |------------------------------|
+ * end|           OFFSET             |
+ *   0|------------------------------|
+ *    |           STRING             |
+ *    |------------------------------|
+ *    |  STRING |     dummy          |
+ *    --------------------------------

+ * @brief GPIOTE handler module.
+ *
+ * @details The GPIOTE handler allows several modules ("users") to share the GPIOTE interrupt,
+ *          each user defining a set of pins able to generate events to the user.
+ *          When a GPIOTE interrupt occurs, the GPIOTE interrupt handler will call the event handler
+ *          of each user for which at least one of the pins generated an event.
+ *
+ *          The GPIOTE users are responsible for configuring all their corresponding pins, except
+ *          the SENSE field, which should be initialized to GPIO_PIN_CNF_SENSE_Disabled.
+ *          The SENSE field will be updated by the GPIOTE module when it is enabled or disabled,
+ *          and also while it is enabled.
+ *
+ *          The module specifies on which pins events should be generated if the pin(s) goes
+ *          from low->high or high->low or both directions.
+ *
+ * @note    Even if the application is using the @ref app_scheduler, the GPIOTE event handlers will
+ *          be called directly from the GPIOTE interrupt handler.
+ *
+ * @warning If multiple users registers for the same pins the behavior for those pins are undefined.

+ * @brief Memory pool implementation
+ *
+ * Memory pool implementation, based on circular buffer data structure, which supports asynchronous
+ * processing of RX data. The current default implementation supports 1 TX buffer and 4 RX buffers.
+ * The memory managed by the pool is allocated from static storage instead of heap. The internal
+ * design of the circular buffer implementing the RX memory layout is illustrated in the picture
+ * below.
+ *
+ * @image html memory_pool.svg "Circular buffer design"
+ *
+ * The expected call order for the RX APIs is as follows:
+ * - hci_mem_pool_rx_produce
+ * - hci_mem_pool_rx_data_size_set
+ * - hci_mem_pool_rx_extract
+ * - hci_mem_pool_rx_consume
+ *
+ * @warning If the above mentioned expected call order is violated the end result can be undefined.
+ *
+ * \par Component specific configuration options
+ *
+ * The following compile time configuration options are available to suit various implementations:
+ * - TX_BUF_SIZE TX buffer size in bytes.
+ * - RX_BUF_SIZE RX buffer size in bytes.
+ * - RX_BUF_QUEUE_SIZE RX buffer element size.

+ *
+ * @brief    HCI transport module implementation.
+ *
+ * This module implements certain specific features from the three-wire UART transport layer,
+ * defined by the Bluetooth specification version 4.0 [Vol 4] part D.
+ *
+ * \par Features supported
+ * - Transmission and reception of Vendor Specific HCI packet type application packets.
+ * - Transmission and reception of reliable packets: defined by chapter 6 of the specification.
+ *
+ * \par Features not supported
+ * - Link establishment procedure: defined by chapter 8 of the specification.
+ * - Low power: defined by chapter 9 of the specification.
+ *
+ * \par Implementation specific behaviour
+ * - As Link establishment procedure is not supported following static link configuration parameters
+ * are used:
+ * + TX window size is 1.
+ * + 16 bit CCITT-CRC must be used.
+ * + Out of frame software flow control not supported.
+ * + Parameters specific for resending reliable packets are compile time configurable (clarifed
+ * later in this document).
+ * + Acknowledgement packet transmissions are not timeout driven , meaning they are delivered for
+ * transmission within same context which the corresponding application packet was received.
+ *
+ * \par Implementation specific limitations
+ * Current implementation has the following limitations which will have impact to system wide
+ * behaviour:
+ * - Delayed acknowledgement scheduling not implemented:
+ * There exists a possibility that acknowledgement TX packet and application TX packet will collide
+ * in the TX pipeline having the end result that acknowledgement packet will be excluded from the TX
+ * pipeline which will trigger the retransmission algorithm within the peer protocol entity.
+ * - Delayed retransmission scheduling not implemented:
+ * There exists a possibility that retransmitted application TX packet and acknowledgement TX packet
+ * will collide in the TX pipeline having the end result that retransmitted application TX packet
+ * will be excluded from the TX pipeline.
+ * - Processing of the acknowledgement number from RX application packets:
+ * Acknowledgement number is not processed from the RX application packets having the end result
+ * that unnecessary application packet retransmissions can occur.
+ *
+ * The application TX packet processing flow is illustrated by the statemachine below.
+ *
+ * @image html hci_transport_tx_sm.svg "TX - application packet statemachine"
+ *
+ * \par Component specific configuration options
+ *
+ * The following compile time configuration options are available, and used to configure the
+ * application TX packet retransmission interval, in order to suite various application specific
+ * implementations:
+ * - MAC_PACKET_SIZE_IN_BITS Maximum size of a single application packet in bits.
+ * - USED_BAUD_RATE Used uart baudrate.
+ *
+ * The following compile time configuration option is available to configure module specific
+ * behaviour:
+ * - MAX_RETRY_COUNT Max retransmission retry count for applicaton packets.

+ * @details This module provides a PWM implementation using timers, GPIOTE, and PPI.
+ *
+ * Resource usage:
+ * - 2 PPI channels per instance + 2 PPI channels per PWM channel.
+ * - 1 PPI group per instance.
+ * - 1 GPIOTE channel per PWM channel.
+ *
+ * For example, a PWM instance with two channels will consume 2 + 4 PPI channels, 1 PPI group, and 2 GPIOTE channels.
+ *
+ * The maximum number of PWM channels per instance is 2.

+ *          when using the Scheduler.
+ *
+ * @section app_scheduler_req Requirements:
+ *
+ * @subsection main_context_logic Logic in main context:
+ *
+ *   - Define an event handler for each type of event expected.
+ *   - Initialize the scheduler by calling the APP_SCHED_INIT() macro before entering the
+ *     application main loop.
+ *   - Call app_sched_execute() from the main loop each time the application wakes up because of an
+ *     event (typically when sd_app_evt_wait() returns).
+ *
+ * @subsection int_context_logic Logic in interrupt context:
+ *
+ *   - In the interrupt handler, call app_sched_event_put()
+ *     with the appropriate data and event handler. This will insert an event into the
+ *     scheduler's queue. The app_sched_execute() function will pull this event and call its
+ *     handler in the main context.
+ *
+ * @if (PERIPHERAL)
+ * For an example usage of the scheduler, see the implementations of
+ * @ref ble_sdk_app_hids_mouse and @ref ble_sdk_app_hids_keyboard.

+ *
+ * @brief Application timer functionality.
+ *
+ * @details This module enables the application to create multiple timer instances based on the RTC1
+ *          peripheral. Checking for time-outs and invocation of user time-out handlers is performed
+ *          in the RTC1 interrupt handler. List handling is done using a software interrupt (SWI0).
+ *          Both interrupt handlers are running in APP_LOW priority level.
+ *
+ * @details When calling app_timer_start() or app_timer_stop(), the timer operation is just queued,
+ *          and the software interrupt is triggered. The actual timer start/stop operation is
+ *          executed by the SWI0 interrupt handler. Since the SWI0 interrupt is running in APP_LOW,
+ *          if the application code calling the timer function is running in APP_LOW or APP_HIGH,
+ *          the timer operation will not be performed until the application handler has returned.
+ *          This will be the case, for example, when stopping a timer from a time-out handler when not using
+ *          the scheduler.
+ *
+ * @details Use the USE_SCHEDULER parameter of the APP_TIMER_INIT() macro to select if the
+ *          @ref app_scheduler should be used or not. Even if the scheduler is
+ *          not used, app_timer.h will include app_scheduler.h, so when
+ *          compiling, app_scheduler.h must be available in one of the compiler include paths.

+ * @brief Define the base class instance
+ *
+ * Macro that defines whole instance variable and fill it with initialization data.
+ *
+ * The tricky part is @c class_config_part.
+ * The configuration data here has to be placed inside brackets.
+ * Then any type of values can be used depending on the type used in @ref APP_USBD_CLASS_TYPEDEF.
+ * If instance does not has any specyfic data, use just empty bracket here.
+ * @code
+ * APP_USBD_CLASS_TYPEDEF(
+ *      some_base_class,
+ *      CLASS_BASE_CONFIGURATION,
+ *      APP_USBD_CLASS_INSTANCE_SPECIFIC_DEC_NONE,
+ *      APP_USBD_CLASS_DATA_SPECIFIC_DEC_NONE
+ * );
+ * APP_USBD_CLASS_INST_DEF(
+ *     some_base_class_inst,
+ *     some_base_class,
+ *     base_class_event_handler,
+ *     CLASS_BASE_CONFIGURATION,
+ *     () // Empty configuration
+ * );
+ * @endcode
+ *
+ * If the type of instance configuration is simple type, just provide initialization value:
+ * @code
+ * APP_USBD_CLASS_TYPEDEF(
+ *      some_base_class,
+ *      CLASS_BASE_CONFIGURATION,
+ *      APP_USBD_CLASS_INSTANCE_SPECIFIC_DEC_NONE,

+ * );
+ * APP_USBD_CLASS_INST_DEF(
+ *     some_base_class_inst,
+ *     some_base_class,
+ *     base_class_event_handler,
+ *     CLASS_BASE_CONFIGURATION,
+ *     (12) // Example values
+ * );
+ * @endcode
+ *
+ * If the type of instance configuration is structure, provide initialization value for the whole structure:
+ * @code
+ * typedef structure
+ * {
+ *     uint32_t p1;
+ *     uint8_t p2;
+ * }my_config_t;
+ *
+ * APP_USBD_CLASS_TYPEDEF(
+ *      some_base_class,
+ *      CLASS_BASE_CONFIGURATION,
+ *      APP_USBD_CLASS_INSTANCE_SPECIFIC_DEC_NONE,
+ *      APP_USBD_CLASS_DATA_SPECIFIC_DEC(my_config_t)
+ * );
+ * APP_USBD_CLASS_INST_DEF(
+ *     some_base_class_inst,
+ *     some_base_class,
+ *     base_class_event_handler,
+ *     CLASS_BASE_CONFIGURATION,
+ *     ({12, 3}) // Example values
+ * );
+ * @endcode
+ *
+ * @param instance_name The name of created instance variable.
+ *                      It would be constant variable and its type would be app_usbd_class_inst_t.
+ * @param type_name     The name of the variable type. It has to be the same type that was passed to
+ *                      @ref APP_USBD_CLASS_TYPEDEF
+ * @param class_methods Class unified interface.
+ * @param interfaces_configs The same configuration data that the one passed to @ref APP_USBD_CLASS_TYPEDEF
+ * @param class_config_part  Configuration data to the type that was declared by class_data_dec when calling
+ *                           @ref APP_USBD_CLASS_TYPEDEF.
+ *                           Configuration data has to be provided in brackets.
+ *                           It would be extracted from brackets and placed in initialization part of configuration structure.
+ *                           See detailed description of this macro for more informations.

+/** @file
+ *
+ * @defgroup ser_phy Serialization PHY
+ * @{
+ * @ingroup ble_sdk_lib_serialization
+ *
+ * @brief PHY layer for serialization.
+ *
+ * @details The @ref ser_phy library declares functions and definitions of data structures and
+ *          identifiers (typedef enum) that are used as API of the serialization PHY layer.
+ *
+ * \par Rationale
+ * Each specific PHY layer (SPI, I2C, UART, low power UART etc.) should provide the same API. This
+ * allows the layer above (the HAL Transport layer), which is responsible for controlling the PHY
+ * layer, memory management, CRC, retransmission etc., to be hardware independent.
+ *
+ *
+ * \par Interlayer communication and control
+ * The PHY layer is controlled by the HAL transport layer by calling functions declared in
+ * the @ref ser_phy library.
+ *
+ * @par
+ * The PHY layer communicates events to the HAL transport layer by calling a callback function.
+ * A handler to this function is passed in the @ref ser_phy_open function. This callback function
+ * should be called with a parameter of type @ref ser_phy_evt_t, filled accordingly to an event to be
+ * passed. Types of supported events are defined in @ref ser_phy_evt_type_t.
+ *
+ * @par
+ * For example, to pass an event indicating that an RX packet has been successfully received, first a
+ * struct of type @ref ser_phy_evt_t must be filled:
+ * @code
+ * ser_phy_evt_t phy_evt;
+ * phy_evt.evt_type = SER_PHY_EVT_RX_PKT_RECEIVED;
+ * phy_evt.evt_params.rx_pkt_received.p_buffer = (pointer to the RX buffer);
+ * phy_evt.evt_params.rx_pkt_received.num_of_bytes = (number of received bytes);
+ * @endcode
+ * Then, the callback function must be called:
+ * @code
+ * events_handler(phy_evt);
+ * @endcode
+ * All functions declared in the @ref ser_phy file (ser_phy.h) must be implemented. Some events specified in
+ * @ref ser_phy_evt_type_t are optional to implement.
+ *
+ * \par Transmitting a packet
+ * Each PHY layer is responsible for adding the PHY header to a packet to be sent. This header
+ * consists of a 16-bit field that carries the packet length (the uint16_encode function defined in
+ * app_util.h should be used to ensure endianness independence). A pointer to a packet to be sent
+ * and length of the packet are parameters of the @ref ser_phy_tx_pkt_send function. When a packet
+ * has been transmitted, an event of type @ref SER_PHY_EVT_TX_PKT_SENT should be emitted.
+ *
+ * \image html ser_phy_transport_tx.svg "TX - interlayer communication"
+ *
+ * \par Receiving a packet
+ * The PHY layer should be able to store only the PHY header (16-bit field carrying the packet
+ * length). After the PHY header has been received, the transmission is stopped and the PHY
+ * layer must send a request to the HAL transport layer for memory to store the packet - an event
+ * of type @ref SER_PHY_EVT_RX_BUF_REQUEST with event parameters defined in
+ * @ref ser_phy_evt_rx_buf_request_params_t (the uint16_decode function defined in app_util.h should
+ * be used for header decoding to ensure endianness independence). The transmission should be
+ * resumed when the @ref ser_phy_rx_buf_set function has been called.
+ *
+ * @par
+ * When the @ref ser_phy_rx_buf_set function parameter equals NULL, there is not
+ * enough memory to store the packet. However, the packet will be received to a dummy location to
+ * ensure continuous communication. After receiving has finished, an event of type
+ * @ref SER_PHY_EVT_RX_PKT_DROPPED is generated.
+ *
+ * \image html ser_phy_transport_rx_dropped.svg "RX dropping - interlayer communication"
+ *
+ * @par
+ * When the @ref ser_phy_rx_buf_set function parameter is different than NULL, the packet is
+ * received to a buffer pointed to by it. After receiving has finished, an event of type
+ * @ref SER_PHY_EVT_RX_PKT_RECEIVED is generated with event parameters defined in
+ * @ref ser_phy_evt_rx_pkt_received_params_t.
+ *
+ * \image html ser_phy_transport_rx_received.svg "RX - interlayer communication"
+ *
+ * \par PHY layer errors

+ * @param[in, out] p_len Pointer the length of the buffer, on return it is filled with the event length.
+ *
+ * @details This call allows the application to pull a BLE event from the BLE stack. The application is signaled that
+ * an event is available from the BLE stack by the triggering of the SD_EVT_IRQn interrupt.
+ * The application is free to choose whether to call this function from thread mode (main context) or directly from the
+ * Interrupt Service Routine that maps to SD_EVT_IRQn. In any case however, and because the BLE stack runs at a higher
+ * priority than the application, this function should be called in a loop (until @ref NRF_ERROR_NOT_FOUND is returned)
+ * every time SD_EVT_IRQn is raised to ensure that all available events are pulled from the BLE stack. Failure to do so
+ * could potentially leave events in the internal queue without the application being aware of this fact.
+ *
+ * Sizing the p_dest buffer is equally important, since the application needs to provide all the memory necessary for the event to
+ * be copied into application memory. If the buffer provided is not large enough to fit the entire contents of the event,
+ * @ref NRF_ERROR_DATA_SIZE will be returned and the application can then call again with a larger buffer size.
+ * The maximum possible event length is defined by @ref BLE_EVT_LEN_MAX. The application may also "peek" the event length
+ * by providing p_dest as a NULL pointer and inspecting the value of *p_len upon return:

+ *
+ * @details This call enables the application to add a vendor specific base UUID to the BLE stack's table, for later

+ * format when dealing with both 16-bit and 128-bit UUIDs without having to check for lengths and having split code
+ * paths. This is accomplished by extending the grouping mechanism that the Bluetooth SIG standard base UUID uses
+ * for all other 128-bit UUIDs. The type field in the @ref ble_uuid_t structure is an index (relative to
+ * @ref BLE_UUID_TYPE_VENDOR_BEGIN) to the table populated by multiple calls to this function, and the UUID field
+ * in the same structure contains the 2 bytes at indexes 12 and 13. The number of possible 128-bit UUIDs available to

+
+  @note
+  SVCs, event and option numbers are split into subranges for each API module.
+  Each module receives its entire allocated range of SVC calls, whether implemented or not,
+  but return BLE_ERROR_NOT_SUPPORTED for unimplemented or undefined calls in its range.
+
+  Note that the symbols BLE_<module>_SVC_LAST is the end of the allocated SVC range,
+  rather than the last SVC function call actually defined and implemented.
+
+  Specific SVC, event and option values are defined in each module's ble_<module>.h file,
+  which defines names of each individual SVC code based on the range start value.

+
+/**
+ * @defgroup groupFilters Filtering Functions

+
+/**
+ * @defgroup groupMatrix Matrix Functions
+ *
+ * This set of functions provides basic matrix math operations.
+ * The functions operate on matrix data structures.  For example,
+ * the type
+ * definition for the floating-point matrix structure is shown
+ * below:
+ * <pre>
+ *     typedef struct
+ *     {
+ *       uint16_t numRows;     // number of rows of the matrix.
+ *       uint16_t numCols;     // number of columns of the matrix.
+ *       float32_t *pData;     // points to the data of the matrix.
+ *     } arm_matrix_instance_f32;
+ * </pre>
+ * There are similar definitions for Q15 and Q31 data types.
+ *
+ * The structure specifies the size of the matrix and then points to
+ * an array of data.  The array is of size <code>numRows X numCols</code>
+ * and the values are arranged in row order.  That is, the
+ * matrix element (i, j) is stored at:
+ * <pre>
+ *     pData[i*numCols + j]
+ * </pre>
+ *
+ * \par Init Functions
+ * There is an associated initialization function for each type of matrix
+ * data structure.
+ * The initialization function sets the values of the internal structure fields.
+ * Refer to the function <code>arm_mat_init_f32()</code>, <code>arm_mat_init_q31()</code>
+ * and <code>arm_mat_init_q15()</code> for floating-point, Q31 and Q15 types,  respectively.
+ *
+ * \par
+ * Use of the initialization function is optional. However, if initialization function is used
+ * then the instance structure cannot be placed into a const data section.
+ * To place the instance structure in a const data
+ * section, manually initialize the data structure.  For example:
+ * <pre>
+ * <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
+ * <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
+ * <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
+ * </pre>
+ * where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
+ * specifies the number of columns, and <code>pData</code> points to the
+ * data array.
+ *
+ * \par Size Checking
+ * By default all of the matrix functions perform size checking on the input and
+ * output matrices.  For example, the matrix addition function verifies that the
+ * two input matrices and the output matrix all have the same number of rows and
+ * columns.  If the size check fails the functions return:
+ * <pre>
+ *     ARM_MATH_SIZE_MISMATCH
+ * </pre>
+ * Otherwise the functions return
+ * <pre>
+ *     ARM_MATH_SUCCESS
+ * </pre>
+ * There is some overhead associated with this matrix size checking.
+ * The matrix size checking is enabled via the \#define
+ * <pre>
+ *     ARM_MATH_MATRIX_CHECK
+ * </pre>
+ * within the library project settings.  By default this macro is defined
+ * and size checking is enabled.  By changing the project settings and
+ * undefining this macro size checking is eliminated and the functions
+ * run a bit faster.  With size checking disabled the functions always
+ * return <code>ARM_MATH_SUCCESS</code>.

+   *
+   * A Proportional Integral Derivative (PID) controller is a generic feedback control
+   * loop mechanism widely used in industrial control systems.
+   * A PID controller is the most commonly used type of feedback controller.
+   *
+   * This set of functions implements (PID) controllers
+   * for Q15, Q31, and floating-point data types.  The functions operate on a single sample
+   * of data and each call to the function returns a single processed value.
+   * <code>S</code> points to an instance of the PID control data structure.  <code>in</code>
+   * is the input sample value. The functions return the output value.
+   *
+   * \par Algorithm:
+   * <pre>
+   *    y[n] = y[n-1] + A0 * x[n] + A1 * x[n-1] + A2 * x[n-2]
+   *    A0 = Kp + Ki + Kd
+   *    A1 = (-Kp ) - (2 * Kd )
+   *    A2 = Kd  </pre>
+   *
+   * \par
+   * where \c Kp is proportional constant, \c Ki is Integral constant and \c Kd is Derivative constant
+   *
+   * \par
+   * \image html PID.gif "Proportional Integral Derivative Controller"
+   *
+   * \par
+   * The PID controller calculates an "error" value as the difference between
+   * the measured output and the reference input.
+   * The controller attempts to minimize the error by adjusting the process control inputs.
+   * The proportional value determines the reaction to the current error,
+   * the integral value determines the reaction based on the sum of recent errors,
+   * and the derivative value determines the reaction based on the rate at which the error has been changing.
+   *
+   * \par Instance Structure
+   * The Gains A0, A1, A2 and state variables for a PID controller are stored together in an instance data structure.
+   * A separate instance structure must be defined for each PID Controller.
+   * There are separate instance structure declarations for each of the 3 supported data types.
+   *
+   * \par Reset Functions
+   * There is also an associated reset function for each data type which clears the state array.
+   *
+   * \par Initialization Functions
+   * There is also an associated initialization function for each data type.
+   * The initialization function performs the following operations:
+   * - Initializes the Gains A0, A1, A2 from Kp,Ki, Kd gains.
+   * - Zeros out the values in the state buffer.
+   *
+   * \par
+   * Instance structure cannot be placed into a const data section and it is recommended to use the initialization function.
+   *
+   * \par Fixed-Point Behavior
+   * Care must be taken when using the fixed-point versions of the PID Controller functions.
+   * In particular, the overflow and saturation behavior of the accumulator used in each function must be considered.
+   * Refer to the function specific documentation below for usage guidelines.

+   * The Park transform can be used to realize the transformation of the <code>Ialpha</code> and the <code>Ibeta</code> currents
+   * from the stationary to the moving reference frame and control the spatial relationship between
+   * the stator vector current and rotor flux vector.
+   * If we consider the d axis aligned with the rotor flux, the diagram below shows the
+   * current vector and the relationship from the two reference frames:

+   *
+   * Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.
+   * The underlying function <code>f(x, y)</code> is sampled on a regular grid and the interpolation process
+   * determines values between the grid points.
+   * Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
+   * Bilinear interpolation is often used in image processing to rescale images.
+   * The CMSIS DSP library provides bilinear interpolation functions for Q7, Q15, Q31, and floating-point data types.
+   *
+   * <b>Algorithm</b>
+   * \par
+   * The instance structure used by the bilinear interpolation functions describes a two dimensional data table.
+   * For floating-point, the instance structure is defined as:
+   * <pre>
+   *   typedef struct
+   *   {
+   *     uint16_t numRows;
+   *     uint16_t numCols;
+   *     float32_t *pData;
+   * } arm_bilinear_interp_instance_f32;
+   * </pre>
+   *
+   * \par
+   * where <code>numRows</code> specifies the number of rows in the table;
+   * <code>numCols</code> specifies the number of columns in the table;
+   * and <code>pData</code> points to an array of size <code>numRows*numCols</code> values.
+   * The data table <code>pTable</code> is organized in row order and the supplied data values fall on integer indexes.
+   * That is, table element (x,y) is located at <code>pTable[x + y*numCols]</code> where x and y are integers.
+   *
+   * \par
+   * Let <code>(x, y)</code> specify the desired interpolation point.  Then define:
+   * <pre>
+   *     XF = floor(x)
+   *     YF = floor(y)
+   * </pre>
+   * \par
+   * The interpolated output point is computed as:
+   * <pre>
+   *  f(x, y) = f(XF, YF) * (1-(x-XF)) * (1-(y-YF))
+   *           + f(XF + 1, YF) * (x-XF)*(1-(y-YF))
+   *           + f(XF, YF + 1) * (1-(x-XF))*(y-YF)
+   *           + f(XF + 1, YF + 1) * (x-XF)*(y-YF)
+   * </pre>
+   * Note that the coordinates (x, y) contain integer and fractional components.
+   * The integer components specify which portion of the table to use while the
+   * fractional components control the interpolation processor.
+   *
+   * \par
+   * if (x,y) are outside of the table boundary, Bilinear interpolation returns zero output.
