9.2
In Compare mode, the 16-bit CCPR1 register value is
constantly compared against the TMR1 register pair
value. When a match occurs, the CCP1 pin is:
• Driven high
• Driven low
• Remains unchanged
The action on the pin is based on the value of control
bits, CCP1M3:CCP1M0 (CCP1CON<3:0>). At the
same time, interrupt flag bit CCP1IF is set.

9.2.1
The user must configure the CCP1 pin as an output by
clearing the TRISB<x> bit.
9.2.2
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.
9.2.3
When generate software interrupt is chosen, the CCP1
pin is not affected. Only a CCP interrupt is generated (if
enabled).
9.2.4
In this mode, an internal hardware trigger is generated
that may be used to initiate an action.
The special event trigger output of CCP1 resets the
TMR1 register pair and starts an A/D conversion (if the
A/D module is enabled). This allows the CCPR1
register to effectively be a 16-bit programmable period
register for Timer1.
