8.0
The CCP (Capture/Compare/PWM) 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 8-1 shows the timer resources of the CCP
Module modes.
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.

0100 = Capture mode, every falling edge
0101 = Capture mode, every rising edge
0110 = Capture mode, every 4th rising edge
0111 = Capture mode, every 16th rising edge
1000 = Compare mode, set output on match (CCPxIF bit is set)
1001 = Compare mode, clear output on match (CCPxIF bit is set)
1010 = Compare mode, generate software interrupt on match (CCPxIF bit is set,
1011 = Compare mode, trigger special event (CCPxIF bit is set, CCPx pin is unaffected);
