@par Example Description
Configuration of the WWDG to periodically update the counter and
generate an MCU WWDG reset when a user button is pressed. The peripheral initialization
uses the LL unitary service functions for optimization purposes (performance and size).
Example Configuration:
Configure the WWDG (Window, Prescaler & Counter) and enable it.
Refresh the WWDG downcounter in the main loop - Led is blinking fastly & continuously
Example Execution:
When User Button is pressed, the Downcounter automatic refresh mechanism is disable and thus, reset will occur.
After a reset when re-entering in the main, RCC WWDG Reset Flag will be checked and if we are back from a WWDG reset the led will be switch ON.
Waiting a new user button pressed to re-activate the WWDG
