8.0
The Capture/Compare/PWM (CCP) module contains a
16-bit register which can operate as a:
• 16-bit Capture register
• 16-bit Compare register
• PWM Master/Slave Duty Cycle register
Capture/Compare/PWM
comprised of two 8-bit registers: CCPR1L (low byte)
and CCPR1H (high byte). The CCP1CON register
controls the operation of CCP. The special event trigger
is generated by a compare match and will clear both
TMR1H and TMR1L registers.

These bits are the two LSbs of the PWM duty cycle. The eight MSbs are found in CCPR1L.
CCP1M3:CCP1M0: CCP1 Mode Select bits
0000 = Capture/Compare/PWM disabled (resets CCP1 module)
0100 = Capture mode, every falling edge
0101 = Capture mode, every rising edge
0110 = Capture mode, every 4th rising edge
0111 = Capture mode, every 16th rising edge
1000 = Compare mode, set output on match (CCP1IF bit is set)
1001 = Compare mode, clear output on match (CCP1IF bit is set)
1010 = Compare mode, generate software interrupt on match (CCP1IF bit is set,
1011 = Compare mode, trigger special event (CCP1IF bit is set, CCP1 pin is unaffected);
11xx = PWM mode
