Part Number: DRV8711
Based on some traffic here, it seems that when the driver is in an operational state (motor spinning, etc) and SLEEPn is asserted for some time, and then de-asserted, a reinitialization is not required, and the motor will be driven the same way as before, with the same settings in the registers. Is this actually confirmed by TI? The datasheet implies it, but not in a way that makes my firmware brethren confident, and thus I need to inquire directly.
The reason is that for our application, we have a need to stop the operation of our stepper based on external signals, without intervention from our uC. The easiest way for me (the hardware guy) to do that is to assert SLEEPn. The uC (and by extension, the firmware team) doesn't need to do anything at all. Or so it seems to me....
Thanks
