PIC18F2331/2431/4331/4431
15.3
In Capture mode, CCPR1H:CCPR1L captures the
16-bit value of the TMR1 register when an event
occurs on pin RC2/CCP1. 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 control bits, CCP1M3:CCP1M0
(CCP1CON<3:0>). When a capture is made, the
interrupt request flag bit, CCP1IF (PIR1<2>), is set; it
must be cleared in software. If another capture occurs
before the value in register CCPR1 is read, the old
captured value is overwritten by the new captured value.
15.3.1
In Capture mode, the RC2/CCP1 pin should be
configured as an input by setting the TRISC<2> bit.
15.3.2
Timer1 must be running in Timer mode or Synchro-
nized Counter mode to be used with the capture
feature. In Asynchronous Counter mode, the capture
operation may not work.

CCP PIN CONFIGURATION
If the RC2/CCP1 pin is configured as an
output, a write to the port can cause a
capture condition.

15.3.3
When the Capture mode is changed, a false capture
interrupt may be generated. The user should keep bit,
CCP1IE (PIE1<2>), clear to avoid false interrupts and
should clear the flag bit, CCP1IF, following any such
change in operating mode.
15.3.4
There are four prescaler settings specified by bits
CCP1M3:CCP1M0. 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. Example 15-1 shows the recom-
mended method for switching between capture
prescalers. This example also clears the prescaler
counter and will not generate the “false” interrupt.
