23.5.4
In Sleep mode, the TMRx 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, TMRx will continue from its
previous state.
23.5.5
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 5.0 “Oscillator Module (With Fail-Safe
Clock Monitor)” for additional details.
23.5.6
Any Reset will force all ports to Input mode and the
CCP registers to their Reset states.

Note:
Disable the PWM pin (CCPx) output driver(s) by
setting the associated TRIS bit(s).
Load the PRx register with the PWM period value.
Configure the CCP module for the PWM mode
by loading the CCPxCON register with the
appropriate values.
Load the CCPRxL register and the DCxBx bits of
the CCPxCON register, with the PWM duty cycle
value.

clearing the associated TRIS bit(s).
SETUP FOR PWM OPERATION
In order to send a complete duty cycle and
period on the first PWM output, the above
steps must be included in the setup
sequence. If it is not critical to start with a
complete PWM signal on the first output,
then step 6 may be ignored.
