I use two pins (RA0, and RA1) two communicate with the TI. Right now I 
am trying to implement the basic functionality that Sami had worked 
towards, which was splitting the card into chunks of X KB (Sami uses 
32KB blocks, I am using 16KB blocks), and so it will use the standard 
Unit-to-Unit communication protocol, with extra packet types in the 
future to allow things like a file manager and a very small filesystem 
(which is partially implemented by the card)
