Remark
The horizontal axis of the above charts indicates the number of steps. The above charts show an example
in the CW (forward) mode.
The current flowing into phases A and B is positive in the direction from OUT pin A to OUT pin B, and
negative in the direction from OUT pin B to OUT pin A. Because the micro step drive mode is in 128 steps,
it equals 1 electrical angle cycle.
