[stella] What is at $029c and $029d?

[Eckhard Stolberg <Eckhard_Stolberg@xxxxxxxxxxxxxxxxxxxxx>]

Dan was nice enough to send me a partly commented copy of the disassembled
SC-BIOS. Currently I'm trying to find out what the rest of the code does,
but there is something I don't understand. In the SC-BIOS there are read
accesses to $029c and read and write accesses to $029d. $029c seems to
work similar to INTIM, but I have no idea what $029d is for. Are they
undocumented RIOT ports or would it be possible, that the SC maps some
of its ports there? Does anyone have an idea?


Thanks, Eckhard Stolberg
