What is the initial state of MAX II devices pre-programming?

What is the initial state of the EPM1270F256I5 before the first programming? I'm trying to determine how to bias it.

Hi Noah,

For GCLK pin, you can assign input clock source to them and do some setting on Quartus.

Else, it will be used as I/O pin.

So are they I/O pins or GCLK pins at default? Remember, I'm not programming my part.
