L6470 Power ON and RESET

Question asked by takahashi.chihiro on Jun 20, 2014
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.
