15.4
In Compare mode, the 16-bit CCPR1 (CCPR2) register
value is constantly compared against the TMR1
register pair value. When a match occurs, the RC2/
CCP1 (RC1/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 CCP1 pin as an output by
clearing the appropriate TRISC bit.

CCP PIN CONFIGURATION
Clearing the CCP1CON register will force
the RC2/CCP1 compare output latch to
the default low level. This is not the
PORTC I/O data latch.
Special Event Trigger will:
RC2/CCP1 Pin
RC1/CCP2 Pin
Reset Timer1, but not set Timer1 interrupt flag bit
and set bit, GO/DONE (ADCON0<1>), which starts an A/D conversion (CCP2 only)

15.4.2
Timer1 must be running in Timer mode or Synchro-
nized 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 Event Trigger output of CCP2 resets the
TMR1 register pair. Additionally, the CCP2 Special
Event Trigger will start an A/D conversion if the A/D
module is enabled.
Note:

SPECIAL EVENT TRIGGER
The Special Event Trigger from the CCP2
module will not set the Timer1 interrupt
flag bit.
