PxM<1:0>: Enhanced PWM Output Configuration bits

If CCPxM<3:2> = 00, 01, 10: (Capture/Compare modes)

xx 

= PxA assigned as Capture/Compare input; PxB, PxC, PxD assigned as port pins

Half-Bridge ECCP Modules

:

If CCPxM<3:2> = 11: (PWM modes)

0x 

= Single output; PxA modulated; PxB assigned as port pin 

1x 

= Half-Bridge output; PxA, PxB modulated with dead-band control

Full-Bridge ECCP Modules

:

If CCPxM<3:2> = 11: (PWM modes)

00 

= Single output; PxA modulated; PxB, PxC, PxD assigned as port pins 

01 

= Full-Bridge output forward; PxD modulated; PxA active; PxB, PxC inactive

10 

= Half-Bridge output; PxA, PxB modulated with dead-band control; PxC, PxD assigned as port

pins 

11

bit 5-4

DCxB<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 CCPRxL.

See 

 to determine full-bridge and half-bridge ECCPs for the device being used.
