18.0
PIC18F47J53 family devices have seven CCP
(Capture/Compare/PWM) modules, designated CCP4
through CCP10. All the modules implement standard
Capture, Compare and Pulse-Width Modulation (PWM)
modes.

CAPTURE/COMPARE/PWM
(CCP) MODULES
CCPxM<3:0> = 1011 will only reset timer and not start A/D conversion on CCPx match.
Throughout this section, generic references
are used for register and bit names that are
the same – except for an ‘x’ variable that
indicates the item’s association with the
specific CCP module. For example, the con-
trol register is named CCPxCON and refers
to CCP4CON through CCP10CON.
Unimplemented: Read as ‘0’
DCxB<1:0>: 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 (DCxB<9:2>) of the duty cycle are found in CCPRxL.
CCPxM<3:0>: 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: Special Event Trigger; reset timer on CCPx match (CCPxIF bit is set)
11xx = PWM mode

R/W-0
Each CCP module contains a 16-bit register that 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 CCP4,
but is equally applicable to CCP5 through CCP10.
