28.6.8 Events

The Clock Failure Detector (CFD) can generate the following output event:
  • Clock Failure (XOSCFAILn): Generated when the Clock Failure status bit is set in the Status register (STATUS.XOSCFAILn). The CFD event is not generated when a Clock Switch bit (STATUS.XOSCCKSWn) in the Status register is set.
Writing a '1' to an Event Output bit in the Event Control register (EVCTRL.CFDEOn) enables the CFD output event for XOSCn. Writing a '0' to this bit disables the CFD output event. Refer to the Event System chapter for details on configuring the event system.
