FULL-BRIDGE MODE

In Full-Bridge Output mode, four pins are used as

outputs; however, only two outputs are active at a time.

In the Forward mode, pin P1A is continuously active

and pin P1D is modulated. In the Reverse mode, pin

P1C is continuously active and pin P1B is modulated.

These are illustrated in Figure 17-6.

P1A, P1B, P1C and P1D outputs are multiplexed with

the PORTC<2>, PORTE<6:5>, and PORTG<4> data

latches. The TRISC<2>, TRISC<6:5>, and TRISG<4>

bits must be cleared to make the P1A, P1B, P1C, and

P1D pins outputs.
