The Watchdog Timer (WDT) can be used to detect system software malfunctions by resetting the device if the WDT is not cleared periodically in software. The user can configure the WDT in Windowed mode or non-Windowed mode. Various WDT time-out periods can be selected using the WDT postscaler. The WDT can also be used to wake the device from Sleep or Idle mode.
