15.5.5 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 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.
