Step clock input. The state machine makes one step on each rising
edge.
Selects the direction of the rotation. HIGH logic level sets clockwise
direction, whereas low logic level sets counterclockwise direction. If
not used, it must be connected to GND or +5 V.
Bridge A source pin. This pin must be connected to power ground
through a sensing power resistor.
RC network pin. A parallel RC network connected between this pin
and ground sets the current controller OFF time of bridge A.
Bridge A output 1.
Ground terminals. In PowerDIP24 and SO24 packages, these pins
are also used for heat dissipation towards the PCB. On PowerSO36
package the slug is connected to these pins.
Bridge B output 1.
RC network pin. A parallel RC network connected between this pin
and ground sets the current controller OFF time of bridge B.
