I think Olin makes a valid point. If you have unused pins, set them as
outputs and leave them unconnected. You were suggesting that it is
necessary to tie all unused pins high or low through resistors, which is
extremely defensive treatment, arguably too defensive. But if you have
an application where setting unused pins as outputs is not enough,
describe it.

Cheerful regards,

Bob
