The following steps should be taken when configuring
the CCP module for standard PWM operation:

4.
5.
6.
20.3.3
The PWM standard mode makes use of one of the 8-bit
Timer2/4/6/8/10 timer resources to specify the PWM
period.
Configuring the CxTSEL<1:0> bits in the CCPTMRSx
register selects which Timer2/4/6/8/10 timer is used.

Note:
Disable the CCPx pin output driver by setting the
associated TRIS bit.
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.
Configure and start Timer2/4/6/8/10:

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.

Preliminary
20.3.4
The PWM period is specified by the PRx register of
Timer2/4/6/8/10. The PWM period can be calculated
using the formula of
EQUATION 20-1:
When TMRx is equal to PRx, the following three events
occur on the next increment cycle:
• TMRx is cleared
• The CCPx pin is set. (Exception: If the PWM duty
• The PWM duty cycle is latched from CCPRxL into
cycle = 0%, the pin will not be set.)
