im using the EP1C3T100C8N, but only actually using 14 IO pins so two banks are unused

p253 has the statement I recall:

"Normal operation does not occur until both power supplies are in their

recommended operating range"

I think i will power the other two banks any way, im not saving any thing by not powering them just a little bit extra routing lol

That would be my advice.
