AD9517 SPI

Hi,

 

On our board we are using AD9517-4 device. the SPI lines are controlled using Xilinx FPGA. after setting it in 4 wire SPI mode the write is happening properly. But whenever we try read operation it happens only one time. after the read operation the device SPI stops working means the write and read both operation doesn't works after that one read operation.

Am i missing some SPI settings for the device? i tried without the read operation then the write operation is functioning properly. 

after giving hardware reset to device the write operation again works.

 

Thanks and Regards,

Nikhil
