I am porting a project framework from an AtMega 64 to a 644PA.
I am having a certain amount of difficulty getting some of the interrupts to execute properly and I suspect that is because the "SIGNAL" names have changed from processor to processor.
I have always found these names to be entirely non-obvious and I cannot even find definitions of them!
Would any of you kind folk point me at where they have been "hidden"?
Thanks in advance,
