Capture Mode
In Capture mode, the CCPRxH:CCPRxL register pair
captures the 16-bit value of the Timer register selected
in the CCPTMRS when an event occurs on the CCPx
pin. An event is defined as one of the following:
Every falling edge
Every rising edge
Every 4th rising edge
Every 16th rising edge
The event is selected by the mode select bits,
CCPxM<3:0> (CCPxCON<3:0>). When a capture is
made, the interrupt request flag bit, CCPxIF (PIR4<x>),
is set; it must be cleared in software. If another capture
occurs before the value in CCPRx is read, the old
captured value is overwritten by the new captured
value.
Figure 19-1 shows the Capture mode block diagram.
19.2.1
CCP PIN CONFIGURATION
In Capture mode, the appropriate CCPx pin should be
configured as an input by setting the corresponding
TRIS direction bit.
19.2.2
TIMER1/3 MODE SELECTION
For the available timers (1/3) to be used for the capture
feature, the used timers must be running in Timer mode
or Synchronized Counter mode. In Asynchronous
Counter mode, the capture operation may not work.
The timer to be used with each CCP module is selected
in the CCPTMRS register. (See Section 19.1.1 “CCP
Details of the timer assignments for the CCP modules
are given in Table 19-2.

CAPTURE MODE OPERATION BLOCK DIAGRAM
Note:
For CCP2 only, the Capture mode can use
the CCP2 input pin as the capture trigger
for CCP2 or the input can function as a
time-stamp through the CAN module. The
CAN module provides the necessary
control and trigger signals.
