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).
