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.CLKFAILEO) 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.
