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 RB3/CCP1/P1A is continu-
ously active and pin RB7/PGD/T1OSI/P1D/KBI3 is
modulated. In the Reverse mode, pin RB6/PGC/
T1OSO/T13CKI/P1C/KBI2 is continuously active and
pin RB2/P1B/INT2 is modulated. These are illustrated
in Figure 15-8.

The TRISB<3:2> and TRISB<7:6> bits must be cleared
to make the P1A, P1B, P1C and P1D pins output.
