Plotting the phase position (Mxx71)
The scale factor is used to scale the phase position
to 0 - 360°. It is = 360 / Ixx71
Plotting the hall sensors (Mxx28)
$700000 Masking enables reading W, V, and U
in bits 20, 21, and 22 respectively
5. Gathering, and plotting data for a short positive travel of the motor should look like:

Primarily, we are interested in two occurrences on the plot; the transition of the halls data between
states 1 & 3, and the point of intersection of Mxx28 and Mxx71 at this transition. This represents the
Hall Effect Zero (HEZ).
