IF it were me I would leave them untied to any external connections, just
program them as inputs with the pullups. That way you can always connect
something to them in a pinch after the board is built and you suddenly
discover you need an input or output line.

Subject: [AVR-Chat] Unused I/O lines


I'm new to AVR's and just want to know what to do with unused I/O
lines.  I assume I would set them to inputs, enable the internal
resistors and tie them to ground.  Is that right?
