A83: Re: TI coding skillz
They probably just stuck it in there for no real purpose and never though
about it at all. Undocumented things are notorious for not working :) I
don't see any real reason they would take it out in 1.10 though. The $0C
page has tons of free space that's not used for anything, so it's not like
it was displacing anything else that would be in the ROM. Ah well...
