The Capture/Compare/PWM module is a peripheral
which allows the user to time and control different
events, and to generate Pulse-Width Modulation
(PWM) signals. In Capture mode, the peripheral allows
the timing of the duration of an event. The Compare
mode allows the user to trigger an external event when
a predetermined amount of time has expired. The
PWM mode can generate Pulse-Width Modulated
signals of varying frequency and duty cycle.
This family of devices contains three Enhanced
Capture/Compare/PWM modules (ECCP1, ECCP2,
and ECCP3) and two standard Capture/Compare/PWM
modules (CCP4 and CCP5).
The Capture and Compare functions are identical for all
five CCP modules (ECCP1, ECCP2, ECCP3, CCP4,
and CCP5). The only differences between CCP
modules are in the Pulse-Width Modulation (PWM)
function. The standard PWM function is identical in
modules, CCP4 and CCP5. In CCP modules ECCP1,
ECCP2, and ECCP3, the Enhanced PWM function has
slight variations from one another. Full-Bridge ECCP
modules have four available I/O pins while Half-Bridge
ECCP modules only have two available I/O pins. See

2: Throughout
module, it is very important to pay close
attention to the register names used. A
number placed after the module acronym
is used to distinguish between separate
modules. For example, the CCP1CON
and
operational aspects of two completely
different CCP modules.
references to a CCP module in any of its
operating modes may be interpreted as
being equally applicable to ECCP1,
ECCP2, ECCP3, CCP4 and CCP5.
Register names, module signals, I/O pins,
and bit names may use the generic
designator 'x' to indicate the use of a
numeral to distinguish a particular module,
when required.
