x = unknown, u = unchanged, – = unimplemented, read as
Generic term for all of the identical registers of this name for all CCP modules, where ‘x’ identifies the individual module
(CCP1 through CCP5). Bit assignments and Reset values for all registers of the same generic name are identical.
If the PWM duty cycle value is longer than
the PWM period, the CCP1 pin will not be
cleared.

Set the PWM period by writing to the PR2
register.
Set the PWM duty cycle by writing to the
CCPR1L register and CCP1CON<5:4> bits.
Make the CCP1 pin an output by clearing the
TRISC<2> bit.
Set the TMR2 prescale value and enable Timer2
by writing to T2CON.
Configure the CCP1 module for PWM operation.
