2. Logic Unit A/B (C/D unit is the same as A/B unit)
Function
This circuit is used to input from the DATA pins micro-step current setting data and to transfer them to the
subsequent stage. By switching the SETUP pin, the data in the mixed decay timing table can be
overwritten.
Note: The RESET and SETUP pins are pulled down in the IC by 10 k
resistor.
When not using these pins, connect them to GND. Otherwise, malfunction may occur.
