14.1
Capture/Compare/PWM Register 1 (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.

TMR1 or TMR3 time-base. Time-base can be different for each CCP.
The compare could be configured for the special event trigger,
which clears either TMR1 or TMR3 depending upon which time-base is used.
The compare(s) could be configured for the special event trigger,
which clears TMR1 or TMR3 depending upon which time-base is used.
The PWMs will have the same frequency and update rate
(TMR2 interrupt).
