+@par Example Description 
+
+This example shows how to store user data in the Backup data registers.
+As the Backup (BKP) domain still powered by VBAT when VDD is switched off, its
+contents are not lost if a battery is connected to VBAT pin.
+
+The program behaves as follows:
+
+1. After startup the program checks if the board has been powered up. If yes, 
+the values in the BKP data registers are checked:
+   - if a battery is connected to the VBAT pin, the values in the BKP data registers
+     are retained
+   - if no battery is connected to the VBAT pin, the values in the BKP data registers
+     are lost
+     
+2. After an external reset, the BKP data registers contents are not checked.
+
+Four LEDs are used to monitor the system state as follows:
+1. LD3 on / LD1 on: a Power On Reset occurred and the values in the BKP data
+   registers are correct
+   
+2. LD3 on / LD2 on: a Power On Reset occurred and the values in the BKP data
+   registers are not correct or they have not yet been programmed (if it is the
+   first time the program is executed)
+   
+3. LD3 off / LD1 off / LD2 off: no Power On Reset occurred
+
+4. LD4 on: program running
+

+  * @brief   CMSIS Cortex-M3 Device Peripheral Access Layer System Source File.
+  * 
+  * 1.  This file provides two functions and one global variable to be called from 
+  *     user application:
+  *      - SystemInit(): Setups the system clock (System clock source, PLL Multiplier
+  *                      factors, AHB/APBx prescalers and Flash settings). 
+  *                      This function is called at startup just after reset and 
+  *                      before branch to main program. This call is made inside
+  *                      the "startup_stm32f10x_xx.s" file.
+  *
+  *      - SystemCoreClock variable: Contains the core clock (HCLK), it can be used
+  *                                  by the user application to setup the SysTick 
+  *                                  timer or configure other parameters.
+  *                                     
+  *      - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
+  *                                 be called whenever the core clock is changed
+  *                                 during program execution.
+  *
+  * 2. After each device reset the HSI (8 MHz) is used as system clock source.
+  *    Then SystemInit() function is called, in "startup_stm32f10x_xx.s" file, to
+  *    configure the system clock before to branch to main program.
+  *
+  * 3. If the system clock source selected by user fails to startup, the SystemInit()
+  *    function will do nothing and HSI still used as system clock source. User can 
+  *    add some code to deal with this issue inside the SetSysClock() function.
+  *
+  * 4. The default value of HSE crystal is set to 8 MHz (or 25 MHz, depedning on
+  *    the product used), refer to "HSE_VALUE" define in "stm32f10x.h" file. 
+  *    When HSE is used as system clock source, directly or through PLL, and you
+  *    are using different crystal you have to adapt the HSE value to your own
+  *    configuration.

+
+@par Example Description 
+
+This example shows how to write/read data to/from Backup data registers and 
+demonstrates the Tamper detection feature.
+
+The associated firmware performs the following:
+
+1. It configures the ANTI_TAMP pin to be active low, and enables the Tamper interrupt.
+
+2. It writes the data to all Backup data registers, then check whether the data were
+correctly written. If yes, LED1 turns on, otherwise LED2 turns on.
+
+3. On applying a low level on the ANTI_TAMP pin (PC.13), the Backup data registers
+are reset and the Tamper interrupt is generated. The corresponding ISR then checks
+whether the Backup data registers are cleared. If yes, LED3 on, otherwise LED4
+turns on.
+
+

+@par Hardware and Software environment 
+
+  - This example runs on STM32F10x Connectivity line, High-Density, Medium-Density, 
+    High-Density Value line, XL-Density, Medium-Density Value line, Low-Density 
+    and Low-Density Value line Devices.
+  
+  - This example has been tested with STMicroelectronics STM32100E-EVAL (High-Density 
+    Value line), STM32100B-EVAL (Medium-Density Value line), STM3210C-EVAL 
+    (Connectivity line), STM3210E-EVAL (High-Density and XL-Density) and STM3210B-EVAL 
+    (Medium-Density) evaluation boards and can be easily tailored to any other 
+    supported device and development board.
+    To select the STMicroelectronics evaluation board used to run the example, 
+    uncomment the corresponding line in stm32_eval.h file (under Utilities\STM32_EVAL)

+  *                                 be called whenever the core clock is changed
+  *                                 during program execution.
+  *
+  * 2. After each device reset the HSI (8 MHz) is used as system clock source.
+  *    Then SystemInit() function is called, in "startup_stm32f10x_xx.s" file, to
+  *    configure the system clock before to branch to main program.
+  *
+  * 3. If the system clock source selected by user fails to startup, the SystemInit()
+  *    function will do nothing and HSI still used as system clock source. User can 
+  *    add some code to deal with this issue inside the SetSysClock() function.
+  *
+  * 4. The default value of HSE crystal is set to 8 MHz (or 25 MHz, depedning on
+  *    the product used), refer to "HSE_VALUE" define in "stm32f10x.h" file. 
+  *    When HSE is used as system clock source, directly or through PLL, and you
+  *    are using different crystal you have to adapt the HSE value to your own
+  *    configuration.
