Hi

I'm using L6470.

It works to move step motor a bit,when the Powered on.

The motor's coil  Voltage was high between  the RESET turn high and First SPI communication is started.(Almost 10ms?CPU's order)

I don't want to move a bit  when the IC powered on.

What is the problem about that?

?SW terminal is LOW when the RESET turn high.
