9.0
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 9-1 shows the
timer resources of the CCP module modes.
CCP1 Module
Capture/Compare/PWM
comprised 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 “PIC
ual” (DS33023).
