FULL-BRIDGE MODE  
In Full-Bridge mode, all four pins are used as outputs.  
An example of Full-Bridge application is shown in  
Figure 22-10.  
In the Forward mode, pin CCPx/PxA is driven to its active  
state, pin PxD is modulated, while PxB and PxC will be  
driven to their inactive state as shown in Figure 22-11.  
In the Reverse mode, PxC is driven to its active state, pin  
PxB is modulated, while PxA and PxD will be driven to  
their inactive state as shown Figure 22-11.  
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.
