8.0
The Capture/Compare/PWM (CCP) 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 CCP. The special event
trigger is generated by a compare match and will clear
both TMR1H and TMR1L registers.
