In Full-Bridge mode, all four pins are used as outputs.
An example of a full-bridge application is provided in
Figure
In the Forward mode, the PxA pin is driven to its active
state, the PxD pin is modulated, while the PxB and PxC
pins will be driven to their inactive state as provided in

In the Reverse mode, the PxC pin is driven to its active
state, the PxB pin is modulated, while the PxA and PxD
pins will be driven to their inactive state as provided

The PxA, PxB, PxC and PxD outputs are multiplexed
with the port data latches. The associated TRIS bits
must be cleared to configure the PxA, PxB, PxC and
PxD pins as outputs.
