Introduction
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 10-bit PWM master/slave Duty Cycle
register. The CCP modules are identical in operation, with the exception of the operation of the
special event trigger.
Each CCP module has 3 registers. Multiple CCP modules may exist on a single device. Through-
out this section we use generic names for the CCP registers. These generic names are shown
in
Table 14-1: Specific to Generic CCP Nomenclature
Table 14-2
shows the interactions between the CCP modules, where CCPx is one CCP module and CCPy
is another CCP module.
