Max 7000S spare I/O pin

I've completed my design with Max 7000S and I about to have PCB made.

I'm using all I/O pins, but one.

I have a spare pull up resistor I could tie this unused pin too.

What should I do?

    IIRC, Altera does not provide a guideline for unused pins for that family.

    Leaving those pins floating is a good option, maybe connected to a test point (never know when you need an extra signal for debugging)
