Question
The reset source identification register (RCC->RSR) of the STM32H7 is zero after a watchdog reset.
After causing a watchdog reset RCC->RSR is showing as 0. I didn't think that was a valid value unless a jump was performed. I check RSR first thing so nothing should be clearing the bits by setting RMVF bit. Other types of reset seem to work. I haven't tried the IWDG yet.
int main(void)
{
u32 RSR = RCC->RSR;
