AD9467 Readback problem

Hi,

we are using AD9467 in our design. I am trying to readback chipid just to verify the spi interface. To readback reg 0x01 I am sending the x"8001" data over sdio line. Expected data 0x50 should be seen on sdio line the next eight clk cycles, but I am unable to see the data . 0x00 is seen. Can you please help me what could have been the issue. Do we need to do anything else for readback.

I have captured sclk and sdio at ADC input . Plz find attached the image of the same.

 

Thanks and Regards,

sumala
