Each Capture/Compare/PWM (CCP) module contains
a 16-bit register which can operate as a:
• 16-bit Capture register
• 16-bit Compare register
• PWM Master/Slave Duty Cycle register
The CCP1, CCP2 and CCP3 modules are identical in
operation, with the exception being the operation of the
special event trigger. Table 9-1 and Table 9-2 show the
resources and interactions of the CCP module(s). In
the following sections, the operation of a CCP module
is described with respect to CCP1. CCP2 and CCP3
operate the same as CCP1, except where noted.
9.1
Capture/Compare/PWM
comprised of two 8-bit registers: CCPR1L (low byte)
and CCPR1H (high byte). The CCP1CON register con-
trols the operation of CCP1. The special event trigger
is generated by a compare match and will clear both
TMR1H and TMR1L registers.

Capture/Compare/PWM Register 2 (CCPR2) is com-
prised of two 8-bit registers: CCPR2L (low byte) and
CCPR2H (high byte). The CCP2CON register controls
the operation of CCP2. The special event trigger is gen-
erated by a compare match; it will clear both TMR1H and
TMR1L registers and start an A/D conversion (if the A/D
module is enabled).
Additional information on CCP modules is available in
the “PICmicro
Manual” (DS33023) and in Application Note AN594
“Using the CCP Module(s)” (DS00594).
9.3
Capture/Compare/PWM Register 3 (CCPR3) is com-
prised of two 8-bit registers: CCPR3L (low byte) and
CCPR3H (high byte). The CCP3CON register controls
the operation of CCP3.
