18.6.7 OSCCTRL Events

The CFD, “Clock Fail Detect”, can generate the following output event:

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