16.4.5
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 16-6.

P1A, P1B, P1C and P1D outputs are multiplexed with
the
PORTD<7> data latches. The TRISC<2>, TRISD<5>,
TRISD<6> and TRISD<7> bits must be cleared to
make the P1A, P1B, P1C and P1D pins outputs.
