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 two Enhanced
Capture/Compare/PWM modules (ECCP1 and ECCP2,)
and two standard Capture/Compare/PWM modules
(CCP3 and CCP4).
The Capture and Compare functions are identical for all
four CCP modules (ECCP1, ECCP2, CCP3 and
CCP4). The only differences between CCP modules
are in the Pulse-Width Modulation (PWM) function. The
standard PWM function is identical in modules, CCP3
and CCP4. In CCP modules ECCP1 and ECCP2, 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
more information.

references to a CCP module in any of its
operating modes may be interpreted as
being equally applicable to ECCP1,
ECCP2, CCP3 and CCP4. 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.
