Is there any way to implement a writeback to EEPROM in ADAU1442 like there is in ADAU1701?
Unfortunately the ADAU1442 hardware does not support writeback to the EEPROM. Therefore, it's a bit harder to make a completely standalone system with the ADAU1442 in comparison to the ADAU1701.
The main advantage of self-boot in an ADAU1442 is the ability to offload the boot sequence from the microcontroller, meaning that a micro with a smaller memory size can be chosen.
A completely standalone system can also be implemented, as long as either there are no user controls, or the state of the user controls do not need to be saved when the system powers down.
