-  * @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

-   The timeout value is also calculated using the highest prescaler (256) and
-   the LSI_VALUE constant. The value of this constant can be changed by the user
-   to take into account possible LSI clock period variations.
-   The timeout value is multiplied by 1000 to be converted in milliseconds. */
