The
module contains a 16-bit register which can operate as
a:
• 16-bit Capture register
• 16-bit Compare register
• PWM Master/Slave Duty Cycle register
Capture/Compare/PWM
comprised of two 8-bit registers: CCPR1L (low byte)
and CCPR1H (high byte).

The CCP1CON register controls the operation of
ECCP. The special event trigger is generated by a
compare match and will clear both TMR1H and TMR1L
registers.
