Full-Bridge Mode
In Full-Bridge mode, all four pins are used as outputs. In practice, this mode is commonly used to run motors, which
provides simple and complete control of speed and rotation direction. There are two such configurations: Full Bridge-
Forward and Full Bridge-Reverse.

Full Bridge - Forward Configuration
In Forward mode the following occurs:
Logic one (1) appears on the P1A pin (pin is high-active);
Pulse sequence appears on the P1D pin; and
Logic zero (0) appears on the P1B and P1C pins (pins are low-active).
