Could someone help me?

I confused about how could ad5629 been read.In datasheet,it says you could read 2 byte data from ad5629.


But in timing picture,after frame 2,master will give a ack through i2c bus.So it means frame 2 is sended by ad5629.Command byte is send by ad5629 when read operation?Is it ture?


My second question is what is the content of my read back frame?I think I could only read the input register of ad5629 through i2c bus.



So I confuse about how could I read ad5629 and what the content of read back frame?

Forgive my poor English. :-)
