Hi ,

 

The AD5121/5141 datasheet does not further description for SPI read back,

I would like to ask about read RDAC register by SPI  process,

I am not sure that the host pulls sync pin as low , sends 2 bytes(control & address / data) , 

and then sends 8 clocks to read the data in RDAC register,

the host pulls sync pin as high. 

Is this procedure correct?

 

I appreciate your message and thank you.

 

best regards

Ray Yang
