9.0
The Capture/Compare/PWM (CCP) module contains a
16-bit register that can operate as a:
• 16-bit Capture register
• 16-bit Compare register
• PWM Master/Slave Duty Cycle register.
Table 9-1 shows the timer resources of the CCP
module modes.
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. The special event trigger is
generated by a compare match which will reset Timer1
and start an A/D conversion (if the A/D module is
enabled).
