To read/write from/to the ADC, put the following pins to the specified levels:
+ ADC SPI Enable = E3 Low (access enabled)
+ DAC SPI Enable = E2 High (access disabled)
+ PLL SPI Enable = F5 High (access disabled)
To read/write from/to the DAC or PLL, put the ADC SPI Enable to High and the corresponding Enable pin to Low. Make sure there is only one pin Low and the other two High.
