14.1
The Capture mode function described in this section is
identical for all CCP and ECCP modules available on
this device family.
Capture mode makes use of the 16-bit Timer
resources, Timer1, Timer3 and Timer5. The timer
resources for each CCP capture function are
independent and are selected using the CCPTMRS0
and CCPTMRS1 registers. When an event occurs on
the CCPx pin, the 16-bit CCPRxH:CCPRxL register
pair captures and stores the 16-bit value of the
TMRxH:TMRxL register pair, respectively. An event is
defined as one of the following and is configured by the
CCPxM<3:0> bits of the CCPxCON register:
• Every falling edge
• Every rising edge
• Every 4th rising edge
• Every 16th rising edge
When a capture is made, the corresponding Interrupt
Request Flag bit CCPxIF of the PIR1, PIR2 or PIR4
register is set. The interrupt flag must be cleared in
software. If another capture occurs before the value in
the CCPRxH:CCPRxL register pair is read, the old
captured value is overwritten by the new captured
value.
TABLE 14-2:
14.1.2
The 16-bit Timer resource must be running in Timer
mode or Synchronized Counter mode for the CCP
module to use the capture feature. In Asynchronous
Counter mode, the capture operation may not work.

(CONFIG3H). Refer to
14.1.3
When the Capture mode is changed, a false capture
interrupt may be generated. The user should keep the
CCPxIE interrupt enable bit of the PIE1, PIE2 or PIE4
register clear to avoid false interrupts. Additionally, the
user should clear the CCPxIF interrupt flag bit of the
PIR1, PIR2 or PIR4 register following any change in
Operating mode.
