16.2.5
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
PGC is continuously active and pin P1B is modulated.
These are illustrated in Figure 16-7.

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.
