P1M<1:0>: Enhanced PWM Output Configuration bits
If CCP1M<3:2> = 00, 01, 10:
xx = P1A assigned as capture/compare input/output; P1B, P1C and P1D assigned as port pins
If CCP1M<3:2> = 11:
00 = Single output: P1A, P1B, P1C and P1D are controlled by steering (see Section 20.4.7 “Pulse
Steering Mode”)
01 = Full-bridge output forward: P1D is modulated; P1A is active; P1B, P1C is inactive
10 = Half-bridge output: P1A, P1B are modulated with dead-band control; P1C and P1D are
assigned as port pins
11 = Full-bridge output reverse: P1B is modulated; P1C is active; P1A and P1D are inactive
DC1B<1:0>: PWM Duty Cycle bit 1 and bit 0
Capture mode:
Unused.
Compare mode:
Unused.
PWM mode:
These bits are the two LSbs of the 10-bit PWM duty cycle. The eight MSbs of the duty cycle 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 = Capture mode
0100 = Capture mode: Every falling edge
0101 = Capture mode: Every rising edge
0110 = Capture mode: Every fourth rising edge
0111 = Capture mode: Every 16^th 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: Trigger special event (ECCP1 resets TMR1 or TMR3, starts A/D conversion,
sets CCP1IF bit)
1100 = PWM mode: P1A and P1C are active-high; P1B and P1D are active-high
1101 = PWM mode: P1A and P1C are active-high; P1B and P1D are active-low
1110 = PWM mode: P1A and P1C are active-low; P1B and P1D are active-high
1111 = PWM mode: P1A and P1C are active-low; P1B and P1D are active-low
