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 in 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 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 frequency dispersion. STM32F0xx - devices provide the capability to measure the LSI frequency (LSI clock - connected internally to TIM16 CH1 input capture). The measured value - can be used to have an IWDG timeout with an acceptable accuracy. - - ##### 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, IWDG_RLR and IWDG_WINR. - (++) 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. - (++) Depending on window parameter: - (+++) If Window Init parameter is same as Window register value, - nothing more is done but reload counter value in order to exit - function with exact time base. - (+++) Else modify Window register. This will automatically reload - watchdog counter. - - (#) 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 - - @endverbatim - ****************************************************************************** - * @attention - * - *
