PIC18F97J60 FAMILY
17.4.5 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 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 17-6.
P1A, P1B, P1C and P1D outputs are multiplexed with
the data latches of the port pins listed in Table 17-1 and
Table 17-3. The corresponding TRIS bits must be
cleared to make the P1A, P1B, P1C and P1D pins
outputs.
