15.0
PIC18F2682/2685 devices have one CCP1 module.
PIC18F4682/4685 devices have two CCP1 (Capture/
Compare/PWM) modules. CCP1, discussed in this
chapter, implements standard Capture, Compare and
Pulse-Width Modulation (PWM) modes.
ECCP1 implements an Enhanced PWM mode. The
ECCP1 implementation is discussed in Section 16.0
“Enhanced
Module”.

PWM mode:
These bits are the two LSbs (bit 1 and bit 0) of the 10-bit PWM duty cycle. The eight MSbs
(DC1B9:DC1B2) of the duty cycle are found in CCPR1L.
CCP1M3:CCP1M0: CCP1 Module Mode Select bits
0000 = Capture/Compare/PWM disabled (resets CCP1 module)
0001 = Reserved
0010 = Compare mode; toggle output on match (CCP1IF bit is set)
0011 = Reserved
0100 = Capture mode; every falling edge or CAN message received (time-stamp)
0101 = Capture mode; every rising edge or CAN message received (time-stamp)
0110 = Capture mode; every 4th rising edge or every 4th CAN message received (time-stamp)
0111 = Capture mode; every 16th rising edge or every 16th CAN message received (time-stamp)
1000 = Compare mode; initialize CCP1 pin low; on compare match, force CCP1 pin high
1001 = Compare mode; initialize CCP pin high; on compare match, force CCP1 pin low
1010 = Compare mode; generate software interrupt on compare match (CCP1IF bit is set,
1011 = Compare mode; trigger special event; reset timer (TMR1 or TMR3, CCP1IF bit is set)

The CCP1 module contains a 16-bit register which can
operate as a 16-bit Capture register, a 16-bit Compare
register or a PWM Master/Slave Duty Cycle register.
For the sake of clarity, all CCP1 module operation in the
following sections is described with respect to CCP1,
but is equally applicable to ECCP1.
Capture/ and Compare operations described in this
chapter apply to all standard and Enhanced CCP1
modules. The operations of PWM mode, described in
Section 15.4 “PWM Mode”, apply to CCP1 only.
