PIC16F882/883/884/886/887
11.6.2
In Full-Bridge mode, all four pins are used as outputs.
An example of Full-Bridge application is shown in
Figure 11-10.
In the Forward mode, pin CCP1/P1A is driven to its
active state, pin P1D is modulated, while P1B and P1C
will be driven to their inactive state as shown in
Figure 11-11.
In the Reverse mode, P1C is driven to its active state,
pin P1B is modulated, while P1A and P1D will be driven
to their inactive state as shown Figure 11-11.

P1A, P1B, P1C and P1D outputs are multiplexed with
the PORT data latches. The associated TRIS bits must
be cleared to configure the P1A, P1B, P1C and P1D
pins as outputs.
