NOTE: toff min is greater than the total fall and
rise time of the spindle output waveforms. This
ensures that a complete off cycle always occurs.
Ideally, toff and the slew rate would be related.
Tond is used by the back EMF detection circuitry
and is nominally about 20% of the total duty cy-
cle.
