21.0 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 two standard Capture/

Compare/PWM modules (CCP1 and CCP2).

The Capture and Compare functions are identical for all

CCP modules.

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.

2: Throughout this section, generic

references to a CCP module in any of its

operating modes may be interpreted as

being equally applicable to CCPx module.

and bit names may use the generic

designator ‘x’ to indicate the use of a

numeral to distinguish a particular module,

when required.
