AD5235 not respond

AD5235 not respond

I'm using the AD5235 in rheostat operation, just to make a variable resistor.

But the resistance between A1 and W1 is always 123k.

When I connected the logic analyser to the SPI wires, I found that SDO is always cero, as shows the image.

The circuit I'm using is the follow:

What I'm doing wrong?

How can I identify if the IC is working fine?
