/*
External clock mode is fine. Don't need to be concerned about noise. Means don't do the 8 us delay thing. 
Noise in the data sehet has more to do with the circuitb oard layout
 
Need to know that bc different control lines on the PC board. 
 
There are two SPI boxes. Use one for the memory and one for the ADC. Arduino should manage on its own.
    Does it give access to the second SPI? not that important.
