PxM<1:0>: Enhanced PWM Output Configuration bits
If CCPxM<3:2> = 00, 01, 10:
xx = PxA assigned as Capture/Compare input/output; PxB, PxC, PxD assigned as port pins
If CCPxM<3:2> = 11:
00 = Single output: PxA modulated; PxB, PxC, PxD assigned as port pins
01 = Full-bridge output forward: P1D modulated; P1A active; P1B, P1C inactive
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
DCxB<1:0>: ECCPx Module PWM Duty Cycle Bit 1 and Bit 0
Capture mode:
Unused.
Compare mode:
Unused.
PWM mode:
These bits are the 2 LSbs of the 10-bit PWM duty cycle. The 8 MSbs of the duty cycle are found in CCPRxL.
CCPxM<3:0>: ECCPx Module Mode Select bits
0000 = Capture/Compare/PWM disabled (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 4th rising edge
0111 = Capture mode; every 16th rising edge
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, sets CCPxIF bit,
ECCPx trigger also starts A/D conversion if A/D module is enabled)⁽¹⁾
1100 = PWM mode; PxA, PxC active-high; PxB, PxD active-high
1101 = PWM mode; PxA, PxC active-high; PxB, PxD active-low
1110 = PWM mode; PxA, PxC active-low; PxB, PxD active-high
1111 = PWM mode; PxA, PxC active-low; PxB, PxD active-low
Note 1: Implemented only for ECCP1 and ECCP2; same as ‘1010’ for ECCP3.
