Revisiting the secret instructions

NetHog

Back in 2004-2005, there was talk about the "secret" instructions (used for debugging). Are these instructions well understood now? Or is there still questions about the breakpoint/OSC instructions?

Most secret instructions (except FIFO) are used in my Taskswitch library for C4SX.

And they are documented at

http://www.sxlist.com/techref/ubicom/secrets.htm

and in the instruction list at

http://www.sxlist.com/techref/ubicom/inst.htm#secret

Please consider adding anything you learn back to that first page by using the little form on the bottom of the page.

Thanks James... I'm tempted to look at the Debug instruction, due to the technical challenge of figuring this out [noparse]:)[/noparse]

I used the FIFO as a quick method to fill/manage a·3 word (6 byte) by 4 buffer for axis moves.
