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 P1A pin is driven to its active
state and the P1D pin is modulated, while the P1B and
P1C pins are driven to their inactive state, as provided in

In the Reverse mode, the P1C pin is driven to its active
state and the P1B pin is modulated, while the P1A and
P1D pins are driven to their inactive state, as provided
Figure
The P1A, P1B, P1C and P1D outputs are multiplexed
with the port data latches. The associated TRIS bits
must be cleared to configure the P1A, P1B, P1C and
P1D pins as outputs.
