Pinout demonstration.

I have completed the AVRxxDU28 pinout now, it is much like the current AVRxxDx28 pinouts.
It hopefully has been formatted correctly, when I get time the QFN will be started.
When all the different pin counts are completed, it will be much faster to generate pinouts as only labels and text will need tweaking to suit the required changes.

Here is the image.

I have left the purple boxes for you to add, but I can add them if you desire.
