OK. I've done some research. I'm not 100% sure what the 3rd function
does from reading over a few TI datasheets. It looks a lot like all
you need to do to get the SD/MD/etc flash cards working is to treat
them like pccards, maybe with throwing a 12V Vpp their way (this
translates to 1.8V at the card), but my look was quick and I don't
have one of these beasts. The 3rd function is for downloading
firmware, but I haven't puzzled out where that firmware comes from or
what it does. Likely something as part of the SD cards, since the S
is Secure. oh, 3rd should be 2nd since you have a 1slot version.
I could attach a small device to the firmware loader, but for now it
will just remain unused.
