CCP Module Configuration
Each Capture/Compare/PWM module is associated
with a control register (generically, CCPxCON) and a
data register (CCPRx). The data register, in turn, is
comprised of two 8-bit registers: CCPRxL (low byte)
and CCPRxH (high byte). All registers are both
readable and writable.

CCP MODULES AND TIMER
RESOURCES
RESOURCES
The CCP modules utilize Timers, 1 through 8, that vary
with the selected mode. Various timers are available to
the CCP modules in Capture, Compare or PWM
modes, as shown in
with the selected mode. Various timers are available to
the CCP modules in Capture, Compare or PWM
modes, as shown in
TABLE 19-1:
CCP MODE – TIMER
RESOURCE
RESOURCE
The assignment of a particular timer to a module is
determined by the timer to CCP enable bits in the
CCPTMRSx registers. (See
determined by the timer to CCP enable bits in the
CCPTMRSx registers. (See
and
.) All of the modules may be active at
once and may share the same timer resource if they
are configured to operate in the same mode
(Capture/Compare or PWM) at the same time.
The CCPTMRS1 register selects the timers for CCP
modules, 7, 6, 5 and 4, and the CCPTMRS2 register
selects the timers for CCP modules, 10, 9 and 8. The
possible configurations are shown in
