Look around firmware/spi.c as well as SpiMaster-related stuff in IOIOLib. BTW, splitting this into multiple transactions, as long as you use writeRead *Async*() and possibly bundling multiple calls between beginBatch() / endBatch() should not introduce a lot of latency between the transactions. I've used this trick in the past to control LED chains (see IOIOHolidayApp).
