2.13.3
The Fail-Safe condition is cleared by either one of the
following:
• Any Reset
• By toggling the SCS1 bit of the OSCCON register
Both of these conditions restart the OST. While the
OST is running, the device continues to operate from
the INTOSC selected in OSCCON. When the OST
times out, the Fail-Safe condition is cleared and the
device automatically switches over to the external clock
source. The Fail-Safe condition need not be cleared
before the OSCFIF flag is cleared.
2.13.4
The FSCM is designed to detect an oscillator failure
after the Oscillator Start-up Timer (OST) has expired.
The OST is used after waking up from Sleep and after

SUMMARY OF REGISTERS ASSOCIATED WITH CLOCK SOURCES
The system clock is normally at a much higher frequency than the sample clock. The relative frequencies in
this example have been chosen for clarity.

any type of Reset. The OST is not used with the EC or
RC Clock modes so that the FSCM will be active as
soon as the Reset or wake-up has completed. When
the FSCM is enabled, the Two-Speed Start-up is also
enabled. Therefore, the device will always be executing
code while the OST is operating.

Due to the wide range of oscillator start-up
times, the Fail-Safe circuit is not active
during oscillator start-up (i.e., after exiting
Reset or Sleep). After an appropriate
amount of time, the user should check the
OSTS bit of the OSCCON register to verify
the oscillator start-up and that the system
clock
completed.
