I've looked through the document, and nowhere do I see the General prefix. It says Digital Output, but never actually General Digital Output. Otherwise I've missed something. – Bjarke Freund-Hansen May 13 '10 at 10:06

They do write "digital output pin for general use", and normally one would refer to these as GPIO for General Purpose I/O. – starblue May 14 '10 at 14:13

It seems that the term is rather TI specific though. I guess I'll just assume General Digital Output is the intented "backronym." Thanks. – Bjarke Freund-Hansen May 15 '10 at 10:32

Btw., the datasheet you are referencing is the exact device that I am working with. Quite a coincidence. ;) – Bjarke Freund-Hansen May 15 '10 at 10:33
