[MAX10] when Boot (CFM0) All IO port High → All port Low

as i know All FPGA have configuration Time.

During Configuration Time, All IO port weak pull up(100kΩ ~ 1MΩ) → All IO port High.

Can i change Pull-up → Pull-Down?

using Max10 Settings?

* My FPGA : 10M50SAE144i7

    Device → Device and pin option... → [Catagory] Configuration → Device Options.. → Set I/O weak pull-ip prior usermode

    Hello,


    Yes, you can set internal pulldown to the IO pins using the pin setting tool.
