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 PWM
master/slave duty cycle register. Both the CCP1 and
CCP2 modules are identical in operation, with the
exception of the operation of the special event trigger.
Table 10-1 and Table 10-2 show the resources and
interactions of the CCP modules(s). In the following
sections, the operation of a CCP module is described
with respect to CCP1. CCP2 operates the same as
CCP1, except where noted.
CCP1 module:
Capture/Compare/PWM Register1 (CCPR1) is com-
prised of two 8-bit registers: CCPR1L (low byte) and
CCPR1H (high byte). The CCP1CON register controls
the operation of CCP1. All are readable and writable.
CCP2 module:
Capture/Compare/PWM Register2 (CCPR2) is com-
prised of two 8-bit registers: CCPR2L (low byte) and
CCPR2H (high byte). The CCP2CON register controls
the operation of CCP2. All are readable and writable.
For use of the CCP modules, refer to the Embedded
Control Handbook, “Using the CCP Modules” (AN594).

Same TMR1 time-base.
The compare should be configured for the special event trigger, which clears TMR1.
The compare(s) should be configured for the special event trigger, which clears TMR1.
The PWMs will have the same frequency, and update rate (TMR2 interrupt).
