33.6.3 WDT Operation in Idle Mode

The WDT module may be used to wake the device from Idle mode. When entering Idle mode, the WDT Run mode counter stops counting and the Power Save mode WDT begins counting from the Reset state until it times out or the device is woken up by an interrupt. Once the device wakes up, either by sleep WDT time-out or by any interrupt, the device resumes the code execution and the Run mode WDT timer.
