3.4 Serial Clock Pin (SCLK)

The host processor provides the serial clock input. SCLK clocks the configuration data into, and conversion data out of, the ADC. When the ADC is appropriately programmed, the serial clock can also be used as the conversion clock. No special configuration is required to run the SCLK in burst mode.
