AD7147 Not responding

Hi,

 

I am trying to connect freescale(MC9S08QE128) with AD7147 by disconnecting the switches between ADuC and AD7147.

 

I am configuring the AD7147 as done in the ADuc sample code from the analog website and i am trying to read back the DEVID, but all i am getting is 255.

 

Please let me know, for the SPI communication, should the initial configuration required or SPI is configured during power up.

 

Also, I have compared the signals between the ADuC and AD7147, and i see its same.

 

But, the interrupt is not generated when configured from the external host.

 

Awaiting response.

 

Thanks

Arun
