hello.I have a design that use MAX10. i noticed that every time I flash it, many I/Os (if not all of them) are going high, according to the documents, the pins should be tri-stated. so first question is, is this phenomenon described anywhere? i couldn't find it... second question, is there any way to avoid this (not talking about adding pull down resistors to my design, try to avoid this). thanks
All unused pins will show the state defined under Assignments/Device/Device and Pin Options/Unused Pins, which is by default "Tri-stated with weak pull-up".There should be no unused IO pins with different behavior.
--- Quote Start --- assume, a brand new chip of max10,when powered up, how will the io pins perform????????!!!!!!! --- Quote End --- If chip is brand new or better when is erased with confign low all pin appear as tristate weak pullup.
