16.2.3
When the Capture mode is changed, a false capture
interrupt may be generated. The user should keep bit,
CCP2IE (PIE2<1>), clear to avoid false interrupts and
should clear the flag bit, CCP2IF, following any such
change in operating mode.
16.2.4
There are four prescaler settings in Capture mode; they
are specified as part of the operating mode selected by
the mode select bits (CCP2M<3:0>). Whenever the
CCP module is turned off, or the CCP module is not in
Capture mode, the prescaler counter is cleared. This
means that any Reset will clear the prescaler counter.
Switching from one capture prescaler to another may
generate an interrupt. Also, the prescaler counter will
not be cleared, therefore, the first capture may be from
a non-zero prescaler.
recommended method for switching between capture
prescalers. This example also clears the prescaler
counter and will not generate the “false” interrupt.
EXAMPLE 16-1:
16.3
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 (CCP2M<3:0>). At the same time, the
interrupt flag bit, CCP2IF, is set.

16.3.1
The user must configure the CCPx pin as an output by
clearing the appropriate TRIS bit.
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
(CCP2M<3:0> = 1010), the CCP2 pin is not affected.
Only a CCP interrupt is generated if enabled and the
CCP2IE bit is set.
16.3.4
CCP1 and CCP2 are both 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 Compare Special Event Trigger mode
(CCP2M<3:0> = 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.
CCP3 is not equipped with a Special Event Trigger.
Selecting the Compare Special Event Trigger mode for
this device (CCP3M<3:0> = 1011) is functionally the
same as selecting the Generate Software Interrupt
mode (CCP3M<3:0> = 1010).

Note:
CCP PIN CONFIGURATION
Clearing the CCPxCON 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.

SOFTWARE INTERRUPT MODE
SPECIAL EVENT TRIGGERS
The Special Event Trigger of CCP1 only
resets Timer1/Timer3 and cannot start an
A/D conversion even when the A/D
Converter is enabled.
