Atmel repeatedly claims (on web site and in datasheets) that the XMega is an "8/16-bit" microcontroller.
Now I've searched the datasheets specifically for 16-bit stuff and for differences between mega1280 and xmega128A1. I expected to find a number of new instructions handling 16-bit operations, but no. I see a lot of differences, but, sadly, fail to see that the XMega is a 16-bit microcontroller any more than the mega 1280. I see both as being 8-bit microcontrollers and that's that.
Does any of you know where that 8/16-bit stuff comes from?
