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 YL,

To clarify, do the I/O pins STAY in tri-state after power-up (but pre-programming)?

Also, what state are the DEV_OE and DEV_CLRn pins in after power-up (but pre-programming)?

Thanks,

Noah
