COMMAND INPUT TIMING CHART

This IC controls the motor by transmitting serial control commands.

Here is an example of the commands.

This IC can change all commands by issuing the LATCH signal once. Therefore, “initialization setting” does not

have to be explicitly performed as shown in the above example.

Immediately after the reset has been cleared, dummy data must be transmitted according to the timing of the

transmit data. For details, refer to SERIAL INTERFACE SPECIFICATIONS.
