AD7734 data register not updating

We are using AD7734 for converting 0-10V voltage digital data.


I am able to detect the ADC. I have written following ocommands to registers.


Address - 0x28 (setup register)

value - 0x01


Address - 0x30 (conv time register)

value - 0xff


Address - 0x38 (Mode register)

value - 0x43.


Then I am reading from Channel 0 data reister address 0x08 (sending 0x48 from SPI for write operation) but the output is always 0x800000 which is default value.


That means the channel data register is not updating.


Kindly suggest us some solution.
