15.0
The CCP (Capture/Compare/PWM) module contains a
16-bit register that can operate as a 16-bit Capture reg-
ister, a 16-bit Compare register or a PWM Master/Slave
Duty Cycle register. Table 15-1 shows the timer
resources required for each of the CCP module modes.
The operation of CCP1 is identical to that of CCP2, with
the exception of the special event trigger. Therefore,
operation of a CCP module is described with respect to
CCP1, except where noted.

These bits are the two LSbs (bit 1 and bit 0) of the 10-bit PWM duty cycle. The upper eight bits
(DCx9:DCx2) of the duty cycle are found in CCPRxL.
