17.0
The PIC18F8722 family of devices all have a total of
five CCP (Capture/Compare/PWM) modules. Two of
these (CCP4 and CCP5) implement standard Capture,
Compare and Pulse-Width Modulation (PWM) modes
and are discussed in this section. The other three
modules
standard Capture and Compare modes, as well as
Enhanced PWM modes. These are discussed in
Section 18.0 “Enhanced Capture/Compare/PWM
(ECCP) Module”.
Each CCP/ECCP module contains a 16-bit register
which can operate as a 16-bit Capture register, a 16-bit
Compare register or a PWM Master/Slave Duty Cycle
register. For the sake of clarity, all CCP module opera-
tions in the following sections are described with
respect to CCP4, but are equally applicable to CCP5.

a specific CCP module are referred to
generically by the use of ‘x’ or ‘y’ in place of

register for CCP4 or CCP5, or ECCP1,
ECCP2 or ECCP3. “CCPxCON” is used
throughout these sections to refer to the

whether the CCP module is a standard or
enhanced implementation.
