Logic levels on Pins from the Factory

What logic levels do the pins on the 10M50DCF484I7C float to from the factory?

 

aka, when I plug this chip into my PCB for the first time before programming it are the pins floating, pulled low, pulled high. Is it a strong pull or a weak pull?

 

I have had issues in the past with the floating logic levels destroying parts of my circuit because the FPGA is not there to pull signals high.

Are you asking state of the Max 10 FPGA IO at reset state ? if yes , answer to your questions is Tri-State.

 

Thank you,

Not the logic levels at the reset state. but the logic levels on the pins right when I take the chip out of the box and power it on.

 

If the chip is in a reset state straight out of the box then this does answer the question.

Flow chart page no : 28/67 below link information about the Configuration Sequence for Intel MAX 10 Devices and each stage IO lines state too.
