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, pin RD4/PSP4/ECCP1/P1A is con-
tinuously active and pin RD7/PSP7/P1D is modulated.
In the Reverse mode, RD6/PSP6/P1C pin is continu-
ously active and RD5/PSP5/P1B pin is modulated.
These are illustrated in Figure 16-5.

P1A, P1B, P1C and P1D outputs are multiplexed with
the PORTD<4:7> data latches. The TRISD<4:7> bits
must be cleared to make the P1A, P1B, P1C and P1D
pins output.
