(CCP) MODULES
CCPxM<3:0> = 1011 will only reset the timer and not start an A/D conversion on a CCP1 match.
Unimplemented: Read as ‘0’

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 (DCx<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
1001 = Compare mode: initialize CCPx pin high; on compare match, force CCPx pin low (CCPxIF bit
1010 = Compare mode: generate software interrupt on compare match (CCPxIF bit is set, CCPx pin
1011 = Compare mode: Special Event Trigger; reset timer; start A/D conversion on CCPx match

R/W-0
Each CCP module contains two 8-bit registers that can
operate as two 8-bit Capture registers, two 8-bit
Compare registers or two PWM Master/Slave Duty
Cycle registers. 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.
