I have a design that uses 10M16SAU169I7G. i noticed that every time I flash it, many I/Os (if not all of them) are going high, I even have a led connected that lights up.

Thank you for the answer and pointing on the datasheet,

Though, I see that it is possible to change User I/Os weak pull up during configuration: https://www.intel.com/content/www/us/en/programmable/documentation/sss1393988509894.html#sss1426059991604 through changing the ICB settings.

Is it possible to configure the weak pull up also when the max10 is not configured? (for example , configuring the icb settings and then erasing the device)

Thanks, Itai.
