</pre></div>Sine table offset values corresponding to hall sensor values when running in the reverse direction. 
<p>
This array contains the sine table offset that corresponds to the hall sensor values when running in the reverse direction. At the moment of a hall change, using the new hall sensor value as index into this table returns the sine table offset that will synchronize the generated sine waves to the back-EMF of the motor.
