Do you want to know detailed self-boot info and limitations like address accessing etc., with ADAU1467? Then please refer page 45 from the ADAU1467's datasheet. For memory and page related entries you have to refer the EEPROM's datasheet.

Instructions like write enable, write instructions etc., You have to verify it in the EEPROM's datasheet and enter it in the EEPROM properties window of sigma studio. Mostly the default settings of sigma studio will be the same for most of the EEPROMs out there. I have four EEPROM brands in hand and all of them have the same instructions as the sigma studio's default.

If the above explanation didn't answer your question, then please post your query with a detailed info.

Regards,

Harish
