Pre-defined fuses ... can't set UPDI pin mode or MVIO mode fuses on AVR64DD28

[tactical-snacks]

i think the pre-defined fuses for the AVR64DD28 leave the UPDI pin in gpio mode and set the MVIO register bit in a reserved configuration, neither yes or no. I could change the reset pin mode and bod level so that works.

perused fuses.py and didn't see an updi pin associated with the dxcore. Also, MVIO seems to be associated with DB series only.

Selected fuses:
-------------------------
[fuse0 / wdtcfg   = 0x00]
[fuse1 / bodcfg   = 0x00]
[fuse2 / osccfg   = 0x00]
[fuse4 / tcd0cfg  = 0x00]
[fuse5 / syscfg0  = 0xC9]
[fuse6 / syscfg1  = 0x06]
[fuse7 / codesize = 0x00]
[fuse8 / bootsize = 0x00]
[lock  / lockbit  = 0x5CC5C55C]
-------------------------

threw these into microchip studio and compared them against the datasheet.

Hi @MCUdude, could you please take a look?

[MCUdude]

I'm a bit busy at the moment, but I'll have a look when I have time. However, I don't recall adding DxCore support to the fuses.py script?

[MCUdude]

I just looked at the commit history. I was me that added DxCore support to the fuses.py script 😄

[MCUdude]

I haven't updated the fuses script to support AVR-DDs yet.
