The PowerSTEP01's datasheet says on page 34 that MIN_SPEED is 12 bits wide.
On page 37, it is described as 13 bits wide.
I suppose that 13 is correct, from code I've read online, but a confirmation (and fix) would be nice. I cannot see the low speed optimization have any effect whatsoever on my phase currents, running from 1 rpm (even lower), to around 8 rpm, where the optimization doesn't seem needed anyway. Any help on how to fix it would be appreciated (running with MIN_SPEED to 0x00 or 0x1fdf, does not affect the current wave at 1 rpm).
