PIC18F6525/6621/8525/8621
16.1
Each Capture/Compare/PWM module is associated
with a control register (generically, CCPxCON) and a
data register (CCPRx). The data register in turn is com-
prised of two 8-bit registers: CCPRxL (low byte) and
CCPRxH (high byte). All registers are both readable
and writable.
16.1.1
The CCP/ECCP modules utilize Timers 1, 2, 3 or 4,
depending on the mode selected. Timer1 and Timer3
are available to modules in Capture or Compare
modes, while Timer2 and Timer4 are available for
modules in PWM mode.
FIGURE 16-1:

Timer1 is used for all Capture
and Compare operations for
all CCP modules. Timer2 is
used for PWM operations for
all CCP modules. Modules

Timer1 and Timer2 are used
for Capture and Compare or
PWM operations for ECCP1
and ECCP2 only (depending
on the mode selected for each
module). Both modules may
use a timer as a common time
base if they are both in
Capture/Compare or PWM
modes.
The other modules use either
Timer3 or Timer4. Modules
may
resource as a common time
base if they are in Capture/
Compare or PWM modes.
TABLE 16-1:
The assignment of a particular timer to a module is
determined by the Timer-to-CCP enable bits in the
T3CON register (Register 14-1, page 143). Depending
on the configuration selected, up to four timers may be
active at once, with modules in the same configuration
(Capture/Compare or PWM) sharing timer resources.
The possible configurations are shown in Figure 16-1.
