ADAU1452 code compatibility

Hello Everybody,

I have a project in production using ADAU1451 where DSP code is loaded by an Application Processor trough I2C.

Now we have some trouble to find the SIGMADSP part number and one of our distributor suggested to use ADAU1452 (still on stock) because the code is fully compatible without any changes.

There is somebody able to confirm that? Unfortunately we cannot change the Hardware and the Firmware because there several thousands of pieces on the field and change the firmware could be a disaster.

Thank a lot in advance to who can help on my question
