14.1
Capture/Compare/PWM Register1 (CCPR1) is com-
prised of two 8-bit registers: CCPR1L (low byte) and
CCPR1H (high byte). The CCP1CON register controls
the operation of CCP1. All are readable and writable.
14.2
Capture/Compare/PWM Register2 (CCPR2) is com-
prised of two 8-bit registers: CCPR2L (low byte) and
CCPR2H (high byte). The CCP2CON register controls
the operation of CCP2. All are readable and writable.

INTERACTION OF TWO CCP MODULES
TMR1 or TMR3 time-base. Time-base can be different for each CCP.
The compare could be configured for the special event trigger, which clears either TMR1
or TMR3, depending upon which time-base is used.
The compare(s) could be configured for the special event trigger, which clears TMR1 or
TMR3 depending upon which time-base is used.
The PWMs will have the same frequency and update rate (TMR2 interrupt).

Advanced Information
14.3
In Capture mode, CCPR1H:CCPR1L captures the
16-bit value of the TMR1 or TMR3 registers when an
event occurs on pin RC2/CCP1. An event is defined as:
• every falling edge
• every rising edge
• every 4th rising edge
• every 16th rising edge
An event is selected by control bits CCP1M3:CCP1M0
(CCP1CON<3:0>). When a capture is made, the inter-
rupt request flag bit CCP1IF (PIR registers) is set. It
must be cleared in software. If another capture occurs
before the value in register CCPR1 is read, the old cap-
tured value will be lost.
14.3.1
In Capture mode, the RC2/CCP1 pin should be config-
ured as an input by setting the TRISC<2> bit.
14.3.2
The timers used with the capture feature (either Timer1
and/or Timer3) must be running in Timer mode or Syn-
chronized Counter mode. In Asynchronous Counter
mode, the capture operation may not work. The timer
used with each CCP module is selected in the T3CON
register.

If the RC2/CCP1 is configured as an out-
put, a write to the port can cause a capture
condition.
