These bits are the two LSbs of the PWM duty cycle. The eight MSbs are found in CCPR1L.
CCP1M<3:0>: ECCP1 Mode Select bits
0000 = Capture/Compare/PWM off (resets ECCP1 module)
0001 = Reserved
0010 = Compare mode: toggle output on match
0011 = Reserved
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: initialize ECCP1 pin low; set output on compare match (set CCP1IF)
1001 = Compare mode: initialize ECCP1 pin high; clear output on compare match (set CCP1IF)
1010 = Compare mode: generate software interrupt only; ECCP1 pin reverts to I/O state
1011 = Compare mode: Special Event Trigger (CCP1 resets Timer, sets CCP1IF bit, and starts A/D conversion
PWM mode:
1100 = PWM mode: P1Aactive-high; P1B active-high
1101 = PWM mode: P1A active-high; P1B active-low
1110 = PWM mode: P1A active-low; P1B active-high
1111 = PWM mode: P1A active-low; P1B active-low
If CCP1M<3:2> = 00, 01, 10:
xx = P1A assigned as Capture/Compare input; P1B assigned as port pins
If CCP1M<3:2> = 11:
00 = Single output; P1A modulated; P1B assigned as port pins
01 = Reserved
10 = Half-Bridge output; P1A, P1B modulated with dead-band control
11 = Reserved
