@par Example Description
How to configure the IWDG peripheral to ensure periodical counter update and
generate an MCU IWDG reset when a User push-button (B1) 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.
LED2 is blinking fast & continuously.
Example Execution:
When User push-button (B1) 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 LED2
will be switch ON.
Waiting a new User push-button (B1) pressed to re-activate the IWDG
