closed) will cause the driver output circuitry to be disabled. Note that the internal sine/cosine
position generator will continue to increment or decrement as long as step clock pulses are
being received by the DSM. The enable input is not synchronized to any other input and may
be changed at any time.

4.3.2 Input timing

The direction input and the microstep resolution inputs are internally synchronized to the
positive going edge of the step clock input. When a step clock transitions from low to high on
the positive going edge, the state of the direction input and microstep resolution settings are
latched. Any changes made to the direction and/or microstep resolution will occur on the rising
edge of the step clock pulse following this change. Run Current and Hold Current changes
are updated immediately (see section 5.2.2).
