8.3.4
In Sleep mode, the TMR2 register will not increment
and the state of the module will not change. If the CCP1
pin is driving a value, it will continue to drive that value.
When the device wakes up, TMR2 will continue from its
previous state.
8.3.5
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.
8.3.6
Any Reset will force all ports to Input mode and the
CCP registers to their Reset states.

8.3.7
The following steps should be taken when configuring
the CCP module for PWM operation:
1.
2.
3.
4.
5.
6.
Disable the PWM pin (CCP1) output drivers by
setting the associated TRIS bit.
Set the PWM period by loading the PR2 register.
Configure the CCP module for the PWM mode
by loading the CCP1CON register with the
appropriate values.
Set the PWM duty cycle by loading the CCPR1L
register and DC1B bits of the CCP1CON register.
Configure and start Timer2:
Enable PWM output after a new PWM cycle has
started:
• Clear the TMR2IF interrupt flag bit of the
• Set the Timer2 prescale value by loading the
• Enable Timer2 by setting the TMR2ON bit of
