PRODUCTION DATA.
SDI is the serial data input line. SDI is used by the host processor to program the internal device registers for device configuration. At the beginning of each data frame, the CS signal goes low and the data on the SDI line are read by the device at every falling edge of the SCLK signal for the next 16 SCLK cycles. Any changes made to the device configuration in a particular data frame are applied to the device on the subsequent falling edge of the CS signal.
