## IWDG_RefreshUntilUserEvent_Init Example Description
How to configure the IWDG peripheral to ensure periodical counter update and generate an MCU IWDG reset when a User push-button is pressed. The peripheral is initialized with LL unitary service functions to optimize for performance and size.
Example Configuration:
Configure the IWDG (prescaler, counter) and enable it. Infinite refresh of the IWDG down-counter done in the main loop.
LED4 is blinking fast & continuously.
Example Execution:
When User push-button is pressed, the down-counter automatic refresh mechanism is disable and thus, reset will occur. After a reset, when re-entering in the main, RCC IWDG Reset Flag will be checked and if we are back from a IWDG reset the LED4 will be switch ON.
Waiting a new User push-button pressed to re-activate the IWDG
System, IWDG, reload counter, MCU Reset
This example runs on STM32C031C6Tx devices.
This example has been tested with NUCLEO-C031C6 board and can be easily tailored to any other supported device and development board.
In order to make the program work, you must do the following :
