While reviewing the code changes to write about all the work required for this project, I found myself fighting to include RTS/CTS support in the final submission. It's been challenging, but as of about five minutes ago I've succeeded in including this feature into the final 1KB hex file.

Accomplishing this took just about every trick I had up my sleeve, but it's done. The only features I would say are missing at this point are serial break generation/detection, parity bit support and framing error detection. While all are "nice to have" features, at this point I'm confident there isn't the remaining space available.

The current code is 7 instructions short of 1KB. Added to this are the configuration register values which take up 14 bytes. It's not clear to me presently if these 14 bytes will be counted in the judges' tally, though I suppose it's better safe than sorry.

If I do find out that the config registers are not counted by the judges, that opens up 7 instructions worth of available space. Probably not enough to add the remaining features, but maybe worth exploring should that situation arise.

With that, I'm off to have a celebratory beer and get ready to ring in the new year. Cheers all!
