WatchDog in DeepSleep State. GR551x

I used the Sleep mode and WDT in GR5515 for battery saving and fault management.

WDT_Refresh function resets watchdog timer counter value. I called this function in main while loop.

But if MCU enter in deep sleep mode, main while loop is not called, I think.

So, the MCU is reset automatically.

Could you let me know the solution?

Thanks.

Hi, you can use app timer to refresh the watchdog before watchdoh is expired.
