+  * @author  MCD Application Team
+  * @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_stm32f1xx_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_stm32f1xx_xx.s" file, to
+  *    configure the system clock before to branch to main program.
+  *
+  * 4. The default value of HSE crystal is set to 8 MHz (or 25 MHz, depending on
+  *    the product used), refer to "HSE_VALUE". 
+  *    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.
+  *

+  * @brief   IWDG HAL module driver.
+  *          This file provides firmware functions to manage the following
+  *          functionalities of the Independent Watchdog (IWDG) peripheral:
+  *           + Initialization and Start functions
+  *           + IO operation functions
+  *
+  @verbatim
+  ==============================================================================
+                    ##### IWDG Generic features #####
+  ==============================================================================
+  [..]
+    (+) The IWDG can be started by either software or hardware (configurable
+        through option byte).
+
+    (+) The IWDG is clocked by the Low-Speed Internal clock (LSI) and thus stays
+        active even if the main clock fails.
+
+    (+) Once the IWDG is started, the LSI is forced ON and both cannot be
+        disabled. The counter starts counting down from the reset value (0xFFF).
+        When it reaches the end of count value (0x000) a reset signal is
+        generated (IWDG reset).
+
+    (+) Whenever the key value 0x0000 AAAA is written in the IWDG_KR register,
+        the IWDG_RLR value is reloaded into the counter and the watchdog reset
+        is prevented.
+
+    (+) The IWDG is implemented in the VDD voltage domain that is still functional
+        in STOP and STANDBY mode (IWDG reset can wake up the CPU from STANDBY).
+        IWDGRST flag in RCC_CSR register can be used to inform when an IWDG
+        reset occurs.
+
+    (+) Debug mode: When the microcontroller enters debug mode (core halted),
+        the IWDG counter either continues to work normally or stops, depending
+        on DBG_IWDG_STOP configuration bit in DBG module, accessible through
+        __HAL_DBGMCU_FREEZE_IWDG() and __HAL_DBGMCU_UNFREEZE_IWDG() macros.
+
+    [..] Min-max timeout value @32KHz (LSI): ~125us / ~32.7s
+         The IWDG timeout may vary due to LSI clock frequency dispersion.
+         STM32F1xx devices provide the capability to measure the LSI clock
+         frequency (LSI clock is internally connected to TIM5 CH4 input capture).
+         The measured value can be used to have an IWDG timeout with an
+         acceptable accuracy.
+
+    [..] Default timeout value (necessary for IWDG_SR status register update):
+         Constant LSI_VALUE is defined based on the nominal LSI clock frequency.
+         This frequency being subject to variations as mentioned above, the
+         default timeout value (defined through constant HAL_IWDG_DEFAULT_TIMEOUT
+         below) may become too short or too long.
+         In such cases, this default timeout value can be tuned by redefining
+         the constant LSI_VALUE at user-application level (based, for instance,
+         on the measured LSI clock frequency as explained above).
+
+                     ##### How to use this driver #####
+  ==============================================================================
+  [..]
+    (#) Use IWDG using HAL_IWDG_Init() function to :
+      (++) Enable instance by writing Start keyword in IWDG_KEY register. LSI
+           clock is forced ON and IWDG counter starts counting down.
+      (++) Enable write access to configuration registers:
+          IWDG_PR and IWDG_RLR.
+      (++) Configure the IWDG prescaler and counter reload value. This reload
+           value will be loaded in the IWDG counter each time the watchdog is
+           reloaded, then the IWDG will start counting down from this value.
+      (++) Wait for status flags to be reset.
+
+    (#) 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
+
