A 24-bit SPI frame is required for writing data to configuration registers. The 24-bit data on SDI, as shown in Figure 32, consists of an 8-bit write command (0000 1000b), an 8-bit register address, and 8-bit data. The write command is decoded on the CS rising edge and the specified register is updated with the 8-bit data specified during the register write operation.
