This status word reflects the status of the internal commutation reference setup process. Refer to the following bit maps:

    bit 0 - (PAF) initiate auto-ranging operation
    bit 1 - (PAF) initiate fine search
    bit 2:7 - (PAF, reserved)
    bit 8 - (Index) ready to adjust commutation reference
    bit 9 - (Index) commutation reference adjustment failed
    bit 10 - (Index) commutation reference adjustment completed
    bit 11 - (Hall) ready to adjust commutation reference
    bit 12 - (Hall) commutation reference adjustment failed.  This indicates that the adjustment attempted to change the commutation reference angle by more than 60 electrical degrees (35 degrees in GPL 3.0 and earlier).  The adjustment was rejected since it was too inconsistent with the initial value set by the hall sensor reading.
    bit 13:15 - (reserved)
