PxM1
PxM<1:0>: Enhanced PWM Output Configuration bits
If CCPxM<3:2> = 00, 01, 10:
xx = PxA is assigned as capture/compare input/output; PxB, PxC and PxD are assigned as port pins
If CCPxM<3:2> = 11:
00 = Single output: PxA, PxB, PxC and PxD are controlled by steering (see
01 = Full-bridge output forward: PxD is modulated; PxA is active; PxB, PxC is inactive
10 = Half-bridge output: PxA, PxB are modulated with dead-band control; PxC and PxD are
11 = Full-bridge output reverse: PxB is modulated; PxC is active; PxA and PxD are inactive
DCxB<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 CCPRxL.
CCPxM<3:0>: ECCPx Mode Select bits
0000 = Capture/Compare/PWM off (resets ECCPx 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 4
0111 = Capture mode, every 16
1000 = Compare mode, initialize ECCPx pin low, set output on compare match (set CCPxIF)
1001 = Compare mode, initialize ECCPx pin high, clear output on compare match (set CCPxIF)
1010 = Compare mode, generate software interrupt only, ECCPx pin reverts to I/O state
1011 = Compare mode, trigger special event (ECCPx resets TMR1 or TMR3, starts A/D conversion,
1100 = PWM mode; PxA and PxC are active-high; PxB and PxD are active-high
1101 = PWM mode; PxA and PxC are active-high; PxB and PxD are active-low
1110 = PWM mode; PxA and PxC are active-low; PxB and PxD are active-high
1111 = PWM mode; PxA and PxC are active-low; PxB and PxD are active-low
