ADAU1452 Program and Parameter  Reading Back

Hi. I am programming ADAU1452 via i2c

with Other Sigma DSP such as adau1761 I am able to readback the Program and Parameter memory .

However when I try this with the ADAU1452 it does not readback the same values that i program it with.

I can read back any of the hardware resisters correctly though.


The reason I wish to do this is to confirm that the DSP is pr grammed OK, As it does not work as expected.

The PLL is Locked. 

Has anyone attempted to readback these memory adresses?
