[AVR Mega 0 series] interrupt vectors

[Simon]

Where do I find the list of AVR-libc / GCC interrupt vectors for the new Mega 0 series? I wish which ever asshole at Microchip or Atmel that decided to recycle the Mega name could be fired! it was the most stupid thing they ever did, you can't find any information about them as any search will bring up decades of information about completely different chips that had that name first. That Mr. D. Head must still be working there........

Literally a few seconds on Google found the Family datasheet listing the interrupt vectors on page 50.

Why are the majority of your posts whinging about everything being someone else's fault?  It's getting quite boring.

it was a stupid idea to re use the name, it causes utter confusion, they are two different types of chip entirely and were in fact the xmega. The list on the datasheet is all well and good, but what are the magic words for the interrupt handler?

For the legacy mega's (see I actually have to change the name now of something that had an accepted name to make it clear which one of the two things with the same name I am talking about) I would go here: https://www.nongnu.org/avr-libc/user-manual/group__avr__interrupts.html , which yea, 5s on google can be found and used.

No such thing exists for the 0 - series.

iom3208.h that is called up in AS has a list that I assume is it.
