The CCPRxH register and a 2-bit internal latch are
used to double-buffer the PWM duty cycle. This
double-buffering is essential for glitchless PWM
operation.
When the CCPRxH and 2-bit latch match TMR2,
concatenated with an internal 2-bit Q clock or 2 bits of
the TMR2 prescaler, the CCPx pin is cleared.
The maximum PWM resolution (bits) for a given PWM
frequency is given by the equation:
TABLE 14-4:
14.4.3
The PWM auto-shutdown features of the Enhanced
CCP module are also available to CCP1 in 28-pin
devices.
discussed in detail in Section 15.4.7 “Enhanced
PWM Auto-Shutdown”.
Auto-shutdown features are not available for CCP2.

Set the PWM period by writing to the PR2
register.
Set the PWM duty cycle by writing to the
CCPRxL register and CCPxCON<5:4> bits.
Make the CCPx pin an output by clearing the
appropriate TRIS bit.
Set the TMR2 prescale value, then enable
Timer2 by writing to T2CON.
Configure the CCPx module for PWM operation.

If the PWM duty cycle value is longer than
the PWM period, the CCP2 pin will not be
