According to the timings in the Max1112's datasheet, the 8 bits of the control byte must be sent on one pin, with a clock pin triggering with each bit, then 8 bits of 0 are sent, and then the 8 bits of recieved information comes in as the clock counts the last 8 clock pulses. According to my source code, I think I've done that. It actually worked, once, somehow.
