SCLK
Digital clock input. This clock directly controls the conversion
and readout processes.
Digital data output. The output samples are clocked out of this
pin on falling edges of the SCLK pin.
Digital data input. The ADC104S101’s Control Register is
loaded through this pin on rising edges of the SCLK pin.
Chip select. On the falling edge of CS, a conversion process
begins. Conversions continue as long as CS is held low.
