14.0
Each CCP (Capture/Compare/PWM) module contains
a 16-bit register which can operate as a 16-bit Capture
register, as a 16-bit Compare register or as a PWM
Master/Slave Duty Cycle register. Table 14-1 shows
the timer resources of the CCP Module modes.

These bits are the two LSbs (bit1 and bit0) of the 10-bit PWM duty cycle. The upper eight bits
(DCx9:DCx2) of the duty cycle are found in CCPRxL.
CCPxM3:CCPxM0: CCPx 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

Initialize CCP pin Low, on compare match force CCP pin High (CCPIF bit is set)
Initialize CCP pin High, on compare match force CCP pin Low (CCPIF bit is set)

The operation of CCP1 is identical to that of CCP2, with
the exception of the special event trigger. Therefore,
operation of a CCP module in the following sections is
described with respect to CCP1.
Table 14-2 shows the interaction of the CCP modules.
