At each rising edge of the STEP input the indexer travels to the next state in the table. The direction is shown
with the DIR pin logic high. If the DIR pin is logic low, the sequence is reversed.
Note
If the step mode is changed on the fly while stepping, the indexer advances to the next valid state for
the new step mode setting at the rising edge of STEP.
Note
While DIR = 0 and the electrical angle is at a full step angle (45, 135, 225, or 315 degrees), two rising
edge pulses on the STEP pin are required in order to advance the indexer after changing from any
microstep mode to the full step mode. The first pulse will induce no change in the electrical angle, the
second pulse will move the indexer to the next full step angle.
The home state is an electrical angle of 45°. This state is entered after power-up, after exiting logic undervoltage
lockout, or after exiting sleep mode.
