You forgot the reset line. Since it is active high on the CS8900A you will 
need to either have another GPIO or use an inverter to alter the RESET# 
signal that resets the micro controller (and keeps it high long enough to 
satisfy the CS8900A). Or you can just try generating a propper sequence 
with an R/C filter and cross your fingers! ;)
