Hello all,

I think iv found a mixup in the hex values with the fuse settings for an ATtiny1614 in Atmel studio 7 and what the datasheet says.

Datasheet: DS40001893B

Fuse settings for SYSCFG0 with  Bits: RSTPINCFG[1:0]: states that setting only bit 3 (0x08)  sets reset pin for UPDI. Here is a screen shot:

I read the fuses (Factory programmed) and AS7 stated the chip is in UPDI mode, so it is apparent that the data sheet (current) is wrong. . 

I have 3 Attiny1614 chips to play with, so i will come back after i program them with my results.

Was able to program fine and re-read the fuses which were the same.
