PIC18F8722 FAMILY
17.1
Each Capture/Compare/PWM module is associated
with a control register (generically, CCPxCON) and a
data register (CCPRx). The data register, in turn, is
comprised of two 8-bit registers: CCPRxL (low byte)
and CCPRxH (high byte). All registers are both
readable and writable.
17.1.1
The CCP/ECCP modules utilize Timers 1, 2, 3 or 4,
depending on the mode selected. Timer1 and Timer3
are available to modules in Capture or Compare
modes, while Timer2 and Timer4 are available for
modules in PWM mode.

Timer1 is used for all Capture
and Compare operations for
all CCP modules. Timer2 is

timer
Timer1 and Timer2 are used
for Capture and Compare or
PWM operations for ECCP1
and ECCP2 only (depending
on the mode selected for each
module). Both modules may
use a timer as a common time
base if they are both in
Capture/Compare or PWM
modes.
The other modules use either
Timer3 or Timer4. Modules
may
resource as a common time
base if they are in Capture/
Compare or PWM modes.
The assignment of a particular timer to a module is
determined by the Timer to CCP enable bits in the
T3CON register (Register 15-1). Depending on the
configuration selected, up to four timers may be active
at once, with modules in the same configuration
(Capture/Compare or PWM) sharing timer resources.
The possible configurations are shown in Figure 17-1.
17.1.2
The pin assignment for ECCP2 (Capture input,
Compare and PWM output) can change, based on
device configuration. The CCP2MX Configuration bit
determines which pin ECCP2 is multiplexed to. By
default, it is assigned to RC1 (CCP2MX = 1). If the
Configuration bit is cleared, ECCP2 is multiplexed with
RE7 in Microcontroller mode, or RE3 in all other
modes.
Changing the pin assignment of ECCP2 does not auto-
matically change any requirements for configuring the
port pin. Users must always verify that the appropriate
TRIS register is configured correctly for ECCP2
operation regardless of where it is located.
