Bit 7 – LOCK: Lock

Lock

Writing this bit to '1' write protects the WDT.CTRLA register.

It is only possible to write this bit to '1'. This bit can only be cleared in debug.

If the PERIOD bits in WDT.CTRLA are different from zero after boot code, Lock will automatically be set.

This bit is under Configuration Change Protection (CCP).

Bit 0 – SYNCBUSY: Synchronization Busy

Synchronization Busy

This bit is set after writing to the WDT.CTRLA register while the data is being synchronized from the system clock domain to the WDT clock domain.

This bit is cleared by system after the synchronization is finished.

This bit is not under Configuration Change Protection (CCP).
