18.1
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.
18.1.1
The CCP modules utilize Timers, 1 through 8, which
varies with the selected mode. Various timers are avail-
able to the CCP modules in Capture, Compare or PWM
modes, as shown in

TABLE 18-1:
The assignment of a particular timer to a module is
determined by the Timer to CCP enable bits in the
CCPTMRSx
Register
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
