CAPTURE/COMPARE/PWM

(CCP) MODULE(s)

Each CCP (Capture/Compare/PWM) module contains

a 16-bit register which can operate as a 16-bit capture

master/slave duty cycle register. Both the CCP1 and

CCP2 modules are identical in operation, with the

exception of the operation of the special event trigger.

Table 10-1 and Table 10-2 show the resources and

interactions of the CCP modules(s). In the following

sections, the operation of a CCP module is described

with respect to CCP1. CCP2 operates the same as

CCP1, except where noted.

CCP1 module:

Capture/Compare/PWM Register1 (CCPR1) is com-

prised of two 8-bit registers: CCPR1L (low byte) and

CCPR1H (high byte). The CCP1CON register controls

the operation of CCP1. All are readable and writable.

CCP2 module:

Capture/Compare/PWM Register2 (CCPR2) is com-

prised of two 8-bit registers: CCPR2L (low byte) and

CCPR2H (high byte). The CCP2CON register controls

the operation of CCP2. All are readable and writable.

For use of the CCP modules, refer to the

Embedded

Control Handbook, “Using the CCP Modules” (AN594).

Capture

Same TMR1 time-base.

Compare

The compare should be conﬁgured for the special event trigger, which clears TMR1.

Compare

The compare(s) should be conﬁgured for the special event trigger, which clears TMR1.

PWM

The PWMs will have the same frequency, and update rate (TMR2 interrupt).
