ade7758 SPI aduino

Category: Hardware
Product Number: ade7758

Hi, recently bought a ade7758. I am trying to enstablish communication between arduino uno and ade7758. 

This is my first analog devices chip. I don't have experience on this. 

I have already set up the schematic of datasheet (page 17 - a).

Is there any method to understand if my communication working? Without AC connection. I am using 5V DC, And I am measuring Vref to gnd 2,42 V.
