Interpretation
Hall sensor 1A (0 = low)
Hall sensor 1B (0 = low)
Hall sensor 1C (0 = low)
Hall sensor 2A (0 = low)
Hall sensor 2B (0 = low)
Hall sensor 2C (0 = low)

GET_PHASE returns the current commutation phase angle, expressed
as the #of encoder counts past the max. value of phase A (cosine of
angle 0). The returned value is a 16-bit integer with a range of 0 to
32,767. This command can be useful for diagnostic purposes, as well
as for amplifier calibration.
