Independent WatchDog

Question asked by Anand A on Dec 28, 2017

We are using Independent WatchDog in our system configured for every 2 seconds. The intention is that if the Refresh is not happening for every 2 seconds, the software will be resetted.


   But, what is observed is that on every power RESET, I can see the RCC->CSR register with Independent WatchDog flag SET. So, this indicates a wrong note to the software that a WatchDog Reset has happened.


   Why is the RCC->CSR SET with IWDG Flag on every power RESET?
