30.5.2 WDT Time-out in Sleep/Idle Mode

When the WDT module times out in Power Save mode, it wakes the device and the WDT Run mode resumes counting.

WDT Sleep/Idle mode event can also trigger a WDT interrupt on wake up from Sleep/Idle mode if IEC0[WDTIE] is enabled.

If the WDT Interrupt Enable bit, WDTIE, is cleared, an interrupt will not be generated on WDT Wakeup event. However, the WDTIF bit will still be set if an interrupt condition occurs. The user can clear the interrupt in the Interrupt Service Routine (ISR) by clearing WDTIF. See the “Interrupt Controller” chapter for more information.
