mm9z1-638:How to determine if a certain address on the EEPROM has encountered an ECC error?

[gumu]

Dear Sir，

Is there a way to determine if an ECC error has occurred at a specific address on an EEPROM? Since reading an address with an ECC error would result in a machine exception, is it possible to preemptively identify if the address has an ECC fault?

Thanks!
