11.6.2 FULL-BRIDGE MODE

In Full-Bridge mode, all four pins are used as outputs.

An example of Full-Bridge application is shown in

Figure 11-10.

In the Forward mode, pin CCP1/P1A is driven to its active

state, pin P1D is modulated, while P1B and P1C will be

driven to their inactive state as shown in Figure 11-11.

In the Reverse mode, P1C is driven to its active state,

pin P1B is modulated, while P1A and P1D will be driven

to their inactive state as shown Figure 11-11.

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.
