15.4
In Compare mode, the 16-bit CCPR1 (CCPR2) register
value is constantly compared against either the
TMR1 register pair value, or the TMR3 register pair
value. When a match occurs, the RC2/CCP1/P1A
(RC1/T1OSI/CCP2) pin:
• Is driven high
• Is driven low
• Toggles output (high-to-low or low-to-high)
• Remains unchanged (interrupt only)
The action on the pin is based on the value of control
bits, CCP1M3:CCP1M0 (CCP2M3:CCP2M0). At the
same time, interrupt flag bit, CCP1IF (CCP2IF), is set.
15.4.1
The user must configure the CCPx pin as an output by
clearing the appropriate TRISC bit.

CCP PIN CONFIGURATION
Clearing the CCP1CON register will force
the RC2/CCP1/P1A compare output latch
to the default low level. This is not the
PORTC I/O data latch.

15.4.2
Timer1 and/or Timer3 must be running in Timer mode,
or Synchronized Counter mode, if the CCP module is
using the compare feature. In Asynchronous Counter
mode, the compare operation may not work.
15.4.3
When generate software interrupt is chosen, the CCP1
pin is not affected. Only a CCP interrupt is generated (if
enabled).
15.4.4
In this mode, an internal hardware trigger is generated
which may be used to initiate an action.
The Special Event Trigger output of CCP1 resets the
TMR1 register pair. This allows the CCPR1 register to
effectively be a 16-bit programmable Period register for
Timer1.
The special trigger output of CCP2 resets either the
TMR1 or TMR3 register pair. Additionally, the CCP2
Special Event Trigger will start an A/D conversion if the
A/D module is enabled.
