PIC16C717/770/771
In Full-Bridge Output mode, four pins are used as out-
puts; however, only two outputs are active at a time. In
the Forward mode, RB3/CCP1/P1A pin is continuously
active, and RB7/T1OSI/P1D pin is modulated. In the
Reverse mode, RB6/T1OSO/T1CKI/P1C pin is contin-
uously active, and RB5/SDO/P1B pin is modulated.

P1A, P1B, P1C and P1D outputs are multiplexed with
PORTB<3> and PORTB<5:7> data latches. TRISB<3>
and TRISB<5:7> bits must be cleared to make the P1A,
P1B, P1C, and P1D pins output.
