AV = ALU overflow. It is set whenever the ALU result was folded from
positive to negative or from negative to positive through 32767/-32768
border.

Hi
I'm corrently playing around with an 2183 ADSP, and writing some test
programs for it. However I fail to understand the logic behind the AV bit
in the astat register. I have to user guide, and I've read and understand
the principle of it however I would like a more indepth knowledge.
Can anyone here explain how it works, and/or have som examples how to test
the bit.
Thank you
