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
CCP/ECCP modules. The difference between CCP
and ECCP modules are in the Pulse-Width Modulation
(PWM) function. In CCP modules, the standard PWM
function is identical. In ECCP modules, the Enhanced
PWM function has either Full-Bridge or Half-Bridge
PWM output. Full-Bridge ECCP modules have four
available I/O pins while Half-Bridge ECCP modules
only have two available I/O pins. ECCP PWM modules
are backward compatible with CCP PWM modules and
can be configured as standard PWM modules. See
Table 14-1
available on each device in this family.

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.
