P1M<1:0>: Enhanced PWM Output Configuration bits(1)
Capture mode:
Unused
Compare mode:
Unused
PWM mode:
If CCP1M<3:2> = 00, 01, 10:
xx = P1A assigned as Capture/Compare input; P1B, P1C, P1D assigned as port pins(1)
If CCP1M<3:2> = 11:
00 = Single output; P1A modulated; P1B, P1C, P1D assigned as port pins
01 = Full-Bridge output forward; P1D modulated; P1A active; P1B, P1C inactive(1)
10 = Half-Bridge output; P1A, P1B modulated with dead-band control; P1C, P1D assigned as port pins
11 = Full-Bridge output reverse; P1B modulated; P1C active; P1A, P1D inactive(1)
DC1B<1:0>: PWM Duty Cycle 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 CCPR1L.

Capture mode: every 4th rising edge
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 TMR1, sets CCP1IF bit, and starts A/D conversion
if A/D module is enabled)
PWM mode:
1100 = PWM mode: P1A, P1C active-high; P1B, P1D active-high
1101 = PWM mode: P1A, P1C active-high; P1B, P1D active-low
1110 = PWM mode: P1A, P1C active-low; P1B, P1D active-high
1111 = PWM mode: P1A, P1C active-low; P1B, P1D active-low
