CAPTURE/COMPARE/PWM

MODULES

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

Table 22-1 for more information.

Note 1:

In devices with more than one CCP

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

CCP2CON

control

the

same

operational aspects of two completely

different CCP modules.

Throughout

this

section,

generic

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.

and bit names may use the generic

designator ‘x’ to indicate the use of a

numeral to distinguish a particular module,

when required.
