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 and the PxD pin is modulated, while the PxB and
PxC pins are driven to their inactive state, as provided in

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