+ ==============================================================================
+ ##### 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.
+ STM32F4xx 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
