DRV8885 previous position question

Team,

Could you advise on the following?

I am using the DRV8885 for controlling a stepper motor.  The datasheet states (page 15) the following:

The home state is an electrical angle of 45°. This state is entered after power-up, after exiting logic undervoltage lockout, or after exiting sleep mode.

Since the motor position is very important to me, I need to know if this means that the motor might be actuated because of what is stated above. Or will the motor be stuck in the position where it was before e.g. the power went down and only be actuated when a new STEP signal is given?

Thanks for your reply.

Tom
