30.3.8 OPERATION IN SLEEP MODE
In Sleep mode, the TMR2 register will not increment
and the state of the module will not change. If the CCPx
pin is driving a value, it will continue to drive that value.
When the device wakes up, TMR2 will continue from its
previous state.
30.3.9
CHANGES IN SYSTEM CLOCK
FREQUENCY
The PWM frequency is derived from the system clock
frequency. Any changes in the system clock frequency
will result in changes to the PWM frequency. See
Section 6.0 “Oscillator Module (with Fail-Safe
Clock Monitor)” for additional details.
30.3.10 EFFECTS OF RESET
Any Reset will force all ports to Input mode and the
CCP registers to their Reset states.
