ADE7953 SPI communication problem

Hy!

 

I am using an Atmel Microcontroller to interface with ADE7953 via SPI.

According to the logic analyzer I sent out the messages correctly but

I did not get any good result.

 

I sent out 10 20 80 which means I read the 0x1020 address which default value

should yield : 0x8040 according to the datasheet of ADE7953: Instead I got FE back.

 

What could be the problem?

 

Here is my waveform:

Thanks for your answers in advance,

Andrew
