External Crystal failure detection in MKE04

   I am using MKE04Z64VLH4 in an application. The controller clock is derived from external crystal of 16 MHz and stepped up through FLL at 40 MHz. Is there any way to detect the external crystal failure so that the controller can be switched to internal clock and then again switched back to external crystal when it becomes normal during run time.



Thanks and best regards,
