Hi. Maybe this question is already covered in other forum, but I just wanna make sure before sending my PCB design to a manufacturer. I wanna use Attiny814 to stablish RS485 communication (using MAX485 by Maxim integrated) and it has a DAC pin, which is an important feature for my project. I read the DS and it states the MCU works with UPDI protocol for programming and debugging, as well as Atmel ICE supports UPDI, reading this url https://microchipdeveloper.com/a.... Will not be any problem to use Atmel Ice to program/debug the ATTiny814 right? I was a little confused because there are some threads that shows Atmel ICE doesn't support 12V for this sort of MCU, so I need to download pyupdi or by arduino programm it. Perhaps those post were old and from that time the ICE didn't support this protocol but it does.
Sorry for restating the info from the web, I just don't want to design my prject and then noticed that I can't use atmel ice
