11.0 CAPTURE/COMPARE/PWM

MODULES (CCP1 AND CCP2)

This device contains one Enhanced Capture/Compare/

PWM (CCP1) and Capture/Compare/PWM module

(CCP2). The CCP1 and CCP2 modules are identical in

operation, with the exception of the Enhanced PWM

features available on CCP1 only. See Section 11.6

“PWM (Enhanced Mode)” for more information.

Note:

CCPRx and CCPx throughout this

document refer to CCPR1 or CCPR2 and

CCP1 or CCP2, respectively.

11.1 Enhanced Capture/Compare/PWM

(CCP1)

The Enhanced Capture/Compare/PWM module is a

peripheral which allows the user to time and control

different events. 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 a Pulse-Width

Modulated signal of varying frequency and duty cycle.

Table 11-1 shows the timer resources required by the

ECCP module.
