Intel Cyclone 10 LP TDI and TMS

Hello,

Please refer to this : https://www.intel.com/content/www/us/en/docs/programmable/683546/current/pull-up-and-pull-down-of-jtag-pins-during.html

You can't disable the internal weak pullup. You can change the VCCIO of the IO bank or change VCC of the JTAG signal.

Side notes: There will be no contention between 3.3V and 2.5V as the Vih/Vil is the same.

regards,

Farabi
