VD must rise before LATCH rises (200 ns MIN.). VD must fall before LATCH falls (200 ns MIN.). In addition to the

operations shown above, an operation in which the VD signal overlaps the LATCH signal is incorrect.

If data related to a stepper motor (addresses 3−1 to 3−4) is input during the wait time, the previous data is ignored.

If data related to a DC motor coil (addresses 4 and 5) is input during the wait time, all the data is valid.
