7.0
Each CCP (Capture/Compare/PWM) module contains
a 16-bit register which can operate as a 16-bit capture
register, as a 16-bit compare register or as a PWM
master/slave Duty Cycle register.
timer resources of the CCP module modes.
The operation of CCP1 is identical to that of CCP2, with
the exception of the special trigger. Therefore, opera-
tion of a CCP module in the following sections is
described with respect to CCP1.
Table 7-2
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.
