21.6.9 Events

The CFD can generate the following output event:

• Clock Failure Detector (CLKFAIL): Generated when the Clock Failure Detector status bit is set in the Status register (STATUS.CLKFAIL). The CFD event is not generated when the Clock Switch bit (STATUS.SWBACK) in the Status register is set.

Writing a '1' to an Event Output bit in the Event Control register (EVCTRL.CFDEO) enables the CFD output event. Writing a '0' to this bit disables the CFD output event. Refer to the Event System chapter for details on configuring the event system.
