14.0
Each CCP (Capture/Compare/PWM) module contains
a 16-bit register that can operate as a 16-bit capture
register, as a 16-bit compare register, or as a PWM
Duty Cycle register. Table 14-1 shows the timer
resources of the CCP module modes.
The operation of CCP1 is identical to that of CCP2, with
the exception of the special event trigger and the CAN
message timestamp received. (Refer to “CAN Module”,

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.

Section 17.0 for CAN operation.) 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.
Register 14-1 shows the CCPx Control registers
(CCPxCON). For the CCP1 module, the register is
called CCP1CON and for the CCP2 module, the regis-
ter is called CCP2CON.
