Be sure to perform initialization (addresses 0 and 1) immediately and after power application and RESET. Transmit

the data of only addresses 0 and 1 for the initialization operation. After the initialization operation, the system can be

controlled simply by inputting driving data (addresses 2 to 5). To execute initialization again, the RESET pin must be

mode high level.

To set a stepper motor, be sure to input the VD signal. If only the VD signal is input, the previous status is held and

the output does not change.
