Clock failure is tested for on the falling edge of the sample clock. If a sample clock falling edge occurs while CM is still set, a clock failure has been detected. This causes the following:

• the FSCM generates an oscillator fail interrupt by setting bit, OSCFIF (PIR2<7>);
• the system clock source is switched to the internal oscillator block (OSCCON is not updated to show the current clock source – this is the Fail-Safe condition); and
• the WDT is

Since the postscaler frequency from the internal oscil- lator block may not be sufficiently stable, it may be desirable to select another clock configuration and enter an alternate power managed mode when breaking PIC18F242 MCU flash memory (see Section 19.3.1 “Special Considerations for Using Two-Speed Start-up” and Section 3.1.3 “Multiple Sleep Commands” for more details). This can be done to attempt a partial recovery, or execute a controlled shutdown.

To use a higher clock speed on wake-up, the INTOSC or postscaler clock sources can be selected to provide a higher clock speed by setting bits, IFRC2:IFRC0 when PIC18F252 microcontroller flash memory program recovery, immediately after Reset. For wake-ups from Sleep, the INTOSC or postscaler clock sources can be selected by setting IFRC2:IFRC0 prior to entering Sleep mode.
