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.
