Occasional ContributorAbout MAX10 IO pin pull-up
It would be helpful if you could tell me about the pull-up of the IO pin of MAX10. 1) In the UG-M10PWR, it is stated that the tri-state and weak pull-up resistors are enabled during power-up due to ...
- I can confirm that MAX10 pins are high impedance (> 10 Mohm) with 0 V supply.

Occasional ContributorThank you for your comment.
In the answer from AqidAyman_Intel, it was said that weak pull-up is disabled by default.
Since it was a machine translation, there was a possibility of a mistranslation, so I checked to see if it was recognized.
Also, I'm sorry for the lack of words.
What I wanted to check in question 4) was whether the I/O pins are floating when the power is off, or whether they are connected to weak pull-ups.
This is because the device connected to the I/O of the circuit under investigation starts up first, and I wanted to know the state of the MAX10's I/O pins when the power is turned off.
We apologize for the inconvenience, but it would be helpful if you could teach us.
