Attn: Randy Dunlap, It means Serial Peripheral Interface. Among other things it is one of the modes of talking to MMC & SD cards, some LCD's, D/As etc. There may be code in the SD09 SD055 drivers. It is a 3 or 4 wire interface -- clk, in, out, and optional extra thing that I don't recall. I think it runs up to about 25Mbits/s.
