14.3
In Compare mode, the 16-bit CCPR2 register value is
constantly compared against either the TMR1 or TMR3
register pair value. When a match occurs, the CCP2
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 (CCP2M3:CCP2M0). At the same time, the
interrupt flag bit, CCP2IF, is set.
14.3.1
The user must configure the CCPx pin as an output by
clearing the appropriate TRIS bit.
14.3.2
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.

CCP PIN CONFIGURATION
Clearing the CCP2CON register will force
the RC1 or RE7 compare output latch
(depending on device configuration) to the
default low level. This is not the PORTC or
PORTE I/O data latch.

14.3.3
When the Generate Software Interrupt mode is chosen
(CCP2M3:CCP2M0 = 1010), the CCP2 pin is not
affected. Only a CCP interrupt is generated if enabled
and the CCP2IE bit is set.
14.3.4
Both CCP modules are equipped with a Special Event
Trigger. This is an internal hardware signal generated
in Compare mode to trigger actions by other modules.
The Special Event Trigger is enabled by selecting
the
(CCP2M3:CCP2M0 = 1011).
For either CCP module, the Special Event Trigger resets
the Timer register pair for whichever timer resource is
currently assigned as the module’s time base. This
allows the CCPRx registers to serve as a programmable
Period register for either timer.
The Special Event Trigger for CCP2 can also start an
A/D conversion. In order to do this, the A/D converter
must already be enabled.
