Teensy 2.0 input pin?

[BReeves]

Data sheet for Stepper IC says to leave an output pin open if not used. I have this pin connected to a pin on the Teensy 2.0 in case I decide down the road it would be useful. The question is what would be the best thing to do with the pin on the Teensy? Not define it at all or set it to an input pin without a pull up?

Thanks

by default it is loaded as input without pullup. all pins are. setting it as INPUT makes no difference, it already is
however, i would suggest you add a comment as to saying what is attached to that pin, for future reference
