16.3
In Compare mode, the 16-bit CCPR1 register value is
constantly compared against either the TMR1 or TMR3
register pair value. When a match occurs, the CCP4
pin can be:
• driven high
• driven low
• toggled (high-to-low or low-to-high)
• remain unchanged (that is, reflects the state of the
The action on the pin is based on the value of the mode
select bits (CCP4M3:CCP4M0). At the same time, the
interrupt flag bit CCP4IF is set.
16.3.1
The user must configure the CCPx pin as an output by
clearing the appropriate TRIS bit.

CCP PIN CONFIGURATION
Clearing the CCP4CON register will force
the RG3/CCP4/P1D compare output latch
to the default low level. This is not the
PORTG I/O data latch.

16.3.2
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.
16.3.3
When the Generate Software Interrupt mode is chosen
(CCP4M3:CCP4M0 = 1010), the CCP4 pin is not
affected. Only a CCP interrupt is generated if enabled
and the CCP4IE bit is set.
16.3.4
Although shown in Figure 16-3, the compare on match
special event triggers are not implemented on CCP4 or
CCP5; they are only available on ECCP1 and ECCP2.
Their operation is discussed in detail in Section 17.2.1
“Special Event Trigger”.
