RE: leave unconnected pins open?

All inputs should have a well defined state. Bi-directional unused GPIO pins can be set to output.

What should I do with unused pins such as gXX_in, rxd1(T17), cts1 (V19) and
other gXX (shared in-/output) ports? Can we leave them unconnected or should
we pull them up by external pullup resistor?
