MODE and nHome pins on DRV8825 motor driver

[newtekuser]

I intend to use full step configuration in my circuit, so per the DRV8825 data sheet I need to set MODE0, MODE1, MODE2 pins to logic low. I do not want to waste any pins on my MCU, so can I just connect each of these pins to GND via a 10K resistors?

Also, if I understand the purpose of the nHome pin, it is used to keep track of steps and useful in motor calibration. Don't think that I care in my project as I'm not looking for perfect accuracy, so can I just connect it to a 10K pull up resistor instead? Or is the drift/step skip really a problem? In my application the motor will only be used sparingly.

Even better, those pins have internal pulldowns, so just leave them unconnected.

The nHOME pin is an output. If you're not going to use it, you can leave it unconnected.

On any chip, outputs usually never need to be connected to anything when unused.

thank you very much folks!
