20.4.2 FULL-BRIDGE MODE

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

An example of a full-bridge application is provided in

Figure 20-8.

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

Figure 20-9.

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 20-9.

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.
