- ******************************************************************************
- * @file stm32f1xx_hal_iwdg.c
- * @author MCD Application Team
- * @version V1.0.4
- * @date 29-April-2016
- * @brief IWDG HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of the Independent Watchdog (IWDG) peripheral:
- * + Initialization and Configuration functions
- * + IO operation functions
- * + Peripheral State functions
- @verbatim
-================================================================================
- ##### IWDG specific features #####
-================================================================================
- [..]
- (+) The IWDG can be started by either software or hardware (configurable
- through option byte).
- (+) The IWDG is clocked by its own dedicated Low-Speed clock (LSI) and
- thus stays active even if the main clock fails.
- (+) Once the IWDG is started, the LSI is forced ON and cannot be disabled
- (LSI cannot be disabled too), and the counter starts counting down from
- the reset value of 0xFFF. When it reaches the end of count value (0x000)
- a system reset is generated.
- (+) The IWDG counter should be refreshed at regular intervals, otherwise the
- watchdog generates an MCU reset when the counter reaches 0.
- (+) The IWDG is implemented in the VDD voltage domain that is still functional
- in STOP and STANDBY mode (IWDG reset can wake-up from STANDBY).
- (+) IWDGRST flag in RCC_CSR register can be used to inform when an IWDG
- reset occurs.
-
- (+) Min-max timeout value at 40KHz (LSI): 0.1us / 26.2s .
- The IWDG timeout may vary due to LSI frequency dispersion. STM32F1xx
- devices provide the capability to measure the LSI frequency (LSI clock
- connected internally to TIM5 CH4 input capture). The measured value
- can be used to have an IWDG timeout with an acceptable accuracy.
- For more information, please refer to the STM32F1xx Reference manual.
- Note: LSI Calibration is only available on: High density, XL-density and Connectivity line devices.
-
- ##### How to use this driver #####
- ==============================================================================
- [..]
- (+) Use IWDG using HAL_IWDG_Init() function to :
- (++) Enable write access to IWDG_PR, IWDG_RLR.
- (++) Configure the IWDG prescaler, counter reload value.
- This reload value will be loaded in the IWDG counter each time the counter
- is reloaded, then the IWDG will start counting down from this value.
- (+) Use IWDG using HAL_IWDG_Start() function to :
- (++) Reload IWDG counter with value defined in the IWDG_RLR register.
- (++) Start the IWDG, when the IWDG is used in software mode (no need
- to enable the LSI, it will be enabled by hardware).
- (+) Then the application program must refresh the IWDG counter at regular
- intervals during normal operation to prevent an MCU reset, using
- HAL_IWDG_Refresh() function.
-
- *** IWDG HAL driver macros list ***
- ====================================
- [..]
- Below the list of most used macros in IWDG HAL driver.
-
- (+) __HAL_IWDG_START: Enable the IWDG peripheral
- (+) __HAL_IWDG_RELOAD_COUNTER: Reloads IWDG counter with value defined in the reload register
- (+) __HAL_IWDG_GET_FLAG: Get the selected IWDG's flag status
