PIC18F2585/2680/4585/4680
15.1
Each Capture/Compare/PWM module is associated
with a control register (CCP1CON or ECCP1CON) and
a data register (CCPR1 or ECCPR1). The data register,
in turn, is comprised of two 8-bit registers: CCPR1L or
ECCPR1L (low byte) and CCPR1H or ECCPR1H (high
byte). All registers are both readable and writable.
15.1.1
The CCP1 modules utilize Timers 1, 2 or 3, depending
on the mode selected. Timer1 and Timer3 are available
to modules in Capture or Compare modes, while
Timer2 is available for modules in PWM mode.

Each module can use TMR1 or TMR3 as the time base. Time base can be different for
each CCP1.
CCP1 can be configured for the special event trigger to reset TMR1 or TMR3
(depending upon which time base is used). Automatic A/D conversions on trigger event
can also be done. Operation of CCP1 could be affected if it is using the same timer as a
time base.
CCP1 can be configured for the special event trigger to reset TMR1 or TMR3
(depending upon which time base is used). Operation of CCP1 could be affected if it is
using the same timer as a time base.
Either module can be configured for the special event trigger to reset the time base.
Automatic A/D conversions on ECCP1 trigger event can be done. Conflicts may occur if
both modules are using the same time base.

Both PWMs will have the same frequency and update rate (TMR2 interrupt).
Preliminary
TABLE 15-1:
The assignment of a particular timer to a module is
determined by the Timer-to-CCP1/ECCP1 enable bits
in the T3CON register (Register 14-1). Both modules
may be active at any given time 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 interactions between the two modules
are summarized in Figure 15-1 and Figure 15-2.
