The Capture/Compare/PWM (CCP) module contains a
16-bit register that can operate as a:
• 16-bit Capture register
• 16-bit Compare register
• PWM Master/Slave Duty Cycle register
Table 9-1 shows the timer resources of the CCP
module modes.
Capture/Compare/PWM Register 1 (CCPR1) is com-
prised of two 8-bit registers: CCPR1L (low byte) and
CCPR1H (high byte). The CCP1CON register controls
the operation of CCP1. The special event trigger is
generated by a compare match which will reset Timer1
and start an A/D conversion (if the A/D module is
enabled).

The CCP module’s input/output pin (CCP1) can be
configured as RB2 or RB3. This selection is set in bit 12
(CCPMX) of the Configuration Word register.
Additional information on the CCP module is available
in the “PICmicro
Manual” (DS33023) and in Application Note AN594,
“Using the CCP Module(s)” (DS00594).
