11.4.2
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.
