REGISTER 9-1:
DS30498C-page 88
bit 7-6
bit 5-4
bit 3-0
CCPxCON: CCPx CONTROL REGISTER (ADDRESS 17h, 1Dh, 97h)
bit 7
Unimplemented: Read as ‘0’
CCPxX:CCPxY: PWM Least Significant bits
Capture mode:
Unused.
Compare mode:
Unused.
PWM mode:
These bits are the two LSbs of the PWM duty cycle. The eight MSbs are found in CCPRxL.
CCPxM3:CCPxM0: CCPx Mode Select bits
0000 = Capture/Compare/PWM disabled (resets CCPx module)
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, CCPx pin is
1011 = Compare mode, trigger special event (CCPxIF bit is set, CCPx pin is unaffected);
11xx = PWM mode
