14.2
In Capture mode, the CCPR1H:CCPR1L register pair
captures the 16-bit value of the TMR1 or TMR3
registers when an event occurs on the corresponding
CCP1 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,
CCP1M<3:0> of the CCP1CON register. When a cap-
ture is made, the interrupt request flag bit, CCP1IF, is
set; it must be cleared by software. If another capture
occurs before the value in register CCPR1 is read, the
old captured value is overwritten by the new captured
value.
14.2.1
In Capture mode, the appropriate CCP1 pin should be
configured as an input by setting the corresponding
TRIS direction bit.
14.2.2
The timers that are to be used with the capture feature
(Timer1 and/or Timer3) must be running in Timer mode
or Synchronized Counter mode. In Asynchronous Coun-
ter mode, the capture operation may not work. The timer

CCP PIN CONFIGURATION
If the CCP1 pin is configured as an output,
a write to the port can cause a capture
condition.

to be used with each CCP module is selected in the

Timer Resources”).
14.2.3
When the Capture mode is changed, a false capture
interrupt may be generated. The user should keep the
CCP1IE interrupt enable bit clear to avoid false inter-
rupts. The interrupt flag bit, CCP1IF, should also be
cleared following any such change in operating mode.
14.2.4
There are four prescaler settings in Capture mode; they
are specified as part of the operating mode selected by
the mode select bits (CCP1M<3:0>). Whenever the
CCP module is turned off or Capture mode is disabled,
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. Example 14-1 shows the
recommended method for switching between capture
prescalers. This example also clears the prescaler
counter and will not generate the “false” interrupt.
