11.0
The 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. Table 11-1 shows the
timer resources of the CCP Module modes.
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.
Additional information on the CCP module is available
in the PICmicro™ Mid-Range Reference Manual,
(DS33023).
