21.2.6
The LPRC oscillator is a component of the Watchdog
Timer (WDT) and oscillates at a nominal frequency of
512 kHz. The LPRC oscillator is the clock source for
the Power-up Timer (PWRT) circuit, WDT and clock
monitor circuits. It may also be used to provide a low
frequency clock source option for applications where
power consumption is critical, and timing accuracy is
not required.
The LPRC oscillator is always enabled at a Power-on
Reset, because it is the clock source for the PWRT.
After the PWRT expires, the LPRC oscillator will remain
ON if one of the following is TRUE:
• The Fail-Safe Clock Monitor is enabled
• The WDT is enabled
• The LPRC oscillator is selected as the system
If one of the above conditions is not true, the LPRC will
shut-off after the PWRT expires.

21.2.7
The Fail-Safe Clock Monitor (FSCM) allows the device
to continue to operate even in the event of an oscillator
failure. The FSCM function is enabled by appropriately
programming the FCKSM configuration bits (Clock
Switch and Monitor Selection bits) in the F
configuration register. If the FSCM function is enabled,
the LPRC Internal oscillator will run at all times (except
during Sleep mode) and will not be subject to control
by the SWDTEN bit.
In the event of an oscillator failure, the FSCM will gen-
erate a Clock Failure Trap event and will switch the sys-
tem clock over to the FRC oscillator. The user will then
have the option to either attempt to restart the oscillator
or execute a controlled shutdown. The user may decide
to treat the Trap as a warm Reset by simply loading the
Reset address into the oscillator fail trap vector. In this
event, the CF (Clock Fail) status bit (OSCCON<3>) is
also set whenever a clock failure is recognized.
In the event of a clock failure, the WDT is unaffected
and continues to run on the LPRC clock.
If the oscillator has a very slow start-up time coming
out of POR, BOR or Sleep, it is possible that the
PWRT timer will expire before the oscillator has
started. In such cases, the FSCM will be activated and
the FSCM will initiate a Clock Failure Trap, and the
COSC<1:0> bits are loaded with FRC oscillator selec-
tion. This will effectively shut-off the original oscillator
that was trying to start.
The user may detect this situation and restart the
oscillator in the Clock Fail Trap ISR.
Upon a clock failure detection, the FSCM module will
initiate a clock switch to the FRC Oscillator as follows:
1.
2.
3.
For the purpose of clock switching, the clock sources
are sectioned into four groups:
1.
2.
3.
4.
The user can switch between these functional groups,
but cannot switch between options within a group. If the
primary group is selected, then the choice within the
group is always determined by the FPR<3:0>
configuration bits.
The COSC bits (OSCCON<13:12>) are loaded
with the FRC Oscillator selection value.
CF bit is set (OSCCON<3>).
OSWEN control bit (OSCCON<0>) is cleared.
