14.0
PIC18F6390/6490/8390/8490 devices have two CCP
(Capture/Compare/PWM) modules, designated CCP1
and CCP2. Both modules implement standard capture,
compare and Pulse-Width Modulation (PWM) modes.

(CCP) MODULES
CCPxM3:CCPxM0 = 1011 will only reset the timer and not start the A/D conversion on the CCPx match.
Unimplemented: Read as ‘0’
DCxB1:DCxB0: PWM Duty Cycle bit 1 and bit 0 for CCPx Module
Capture mode:
Unused.
Compare mode:
Unused.
PWM mode:
These bits are the two Least Significant bits (bit 1 and bit 0) of the 10-bit PWM duty cycle. The eight Most
Significant bits (DCxB9:DCxB2) of the duty cycle are found in CCPRxL.
CCPxM3:CCPxM0: CCPx Module Mode Select bits
0000 = Capture/Compare/PWM disabled (resets CCPx module)
0001 = Reserved
0010 = Compare mode, toggle output on match (CCPxIF bit is set)
0011 = Reserved
0100 = Capture mode, every falling edge
0101 = Capture mode, every rising edge
0110 = Capture mode, every 4th rising edge
0111 = Capture mode, every 16th rising edge
1000 = Compare mode: initialize CCPx pin low; on compare match, force CCPx pin high (CCPxIF bit is set)
1001 = Compare mode: initialize CCPx pin high; on compare match, force CCPx pin low (CCPxIF bit is set)
1010 = Compare mode: generate software interrupt on compare match (CCPxIF bit is set, CCPx pin
1011 = Compare mode: trigger special event, reset timer, start A/D conversion on CCPx match (CCPxIF

Each CCP 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 CCP module operation in the
following sections is described with respect to CCP2,
but is equally applicable to CCP1.
