15.1
Both CCP1 and CCP2 are comprised of two 8-bit
registers: CCPRxL (low byte) and CCPRxH (high byte),
1
operation of CCPx. All are readable and writable.
Table 15-1 shows the timer resources of the CCP
module modes.
TABLE 15-1:
15.2
In Capture mode, CCPRxH:CCPRxL captures the
16-bit value of the TMR1 or TMR3 register when an
event occurs on pin CCPn. An event is defined as:
• every falling edge
• every rising edge
• every 4th rising edge
• every 16th rising edge

The compare could be configured for the special event trigger which clears either TMR1

The PWMs will have the same frequency and update rate (TMR2 interrupt).

PIC18F6585/8585/6680/8680
An event is selected by control bits CCPxM3:CCPxM0
(CCPxCON<3:0>). When a capture is made, the inter-
rupt request flag bit, CCPxIF (PIR registers), is set. It
must be cleared in software. If another capture occurs
before the value in register CCPRx is read, the old
captured value will be lost.
15.2.1
In Capture mode, the CCPx pin should be configured
as an input by setting the appropriate TRIS bit.
15.2.2
The timer used with each CCP module is selected in
the T3CCP2:T3CCP1 bits of the T3CON register. The
timers used with the capture feature (either Timer1 or
Timer3) must be running in Timer mode or Synchro-
nized Counter mode. In Asynchronous Counter mode,
the capture operation may not work.
Note:
Interaction
CCP PIN CONFIGURATION
If the CCPx is configured as an output, a
write to the port can cause a capture
condition.
