Serial Port Operation
The AD9856 serial control interface is designed to be compatible with most synchronous transfer formats. The
interface allows read/write access to all registers that configure the AD9856. Single or multiple byte transfers are
supported as well as MSB or LSB transfer formats. The AD9856’s serial interface port can be configured as a single
pin I/O (SDIO) or two unidirectional pins for in/out (SDIO/SDO).
Communicating with the AD9856 occurs in two phases. The first phase of every communication cycle is the writing of
an instruction byte. The second phase is the data transfer as specified by the instruction byte.

All data input to the AD9856 is registered on the rising edge of SCLK. All data is driven out of the AD9856 on the
falling edge of SCLK.
The instruction byte contains the following information as shown below (see Table IV):

R/W (Bar) - Bit 7 of the instruction byte determines whether a read or write data transfer will occur after the
instruction byte write. Logic high indicates read operation.
