In connection with a SPI bus there is typically a number of GDO pins used for interrupting the master or the slave of the SPI connection. But what is GDO an acronym for?
A:
General Digital Output
See for example http://focus.ti.com/lit/ds/symlink/cc2500.pdf.

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.

They do write "digital output pin for general use", and normally one would refer to these as GPIO for General Purpose I/O.

It seems that the term is rather TI specific though. I guess I'll just assume General Digital Output is the intented "backronym." Thanks.

Btw., the datasheet you are referencing is the exact device that I am working with. Quite a coincidence. ;)
