PIC16F193X/LF193X
22.4.2
In Full-Bridge mode, all four pins are used as outputs.
An example of Full-Bridge application is shown in
Figure 22-10.
In the Forward mode, pin CCPx/PxA is driven to its active
state, pin PxD is modulated, while PxB and PxC will be
driven to their inactive state as shown in Figure 22-11.
In the Reverse mode, PxC is driven to its active state, pin
PxB is modulated, while PxA and PxD will be driven to
their inactive state as shown Figure 22-11.
PxA, PxB, PxC and PxD outputs are multiplexed with
the PORT data latches. The associated TRIS bits must
be cleared to configure the PxA, PxB, PxC and PxD
pins as outputs.
