U
Unimplemented: Read as ’0’
DCnB<1:0>: 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 CCPRnL.
CCPnM<3:0>: CCPx Mode Select bits
0000 = Capture/Compare/PWM off (resets CCPn 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 (CCPnIF bit is set)
1001 = Compare mode, clear output on match (CCPnIF bit is set)
1010 = Compare mode, generate software interrupt on match (CCPnIF bit is set, CCPn pin is unaffected)
1011 = Compare mode, trigger special event (CCPnIF bit is set; CCPn resets TMR1or TMR3)
11xx = PWM mode
