In AN11983 Using the S32K1xx EEPROM Functionality, the EEPROM data recovery mechanism is described as below:


Statement about EEPROM data recovery

Literally, the compromised record being replaced by the previous reliable record is done DURING THE NEXT EEE WRITE. This is quite ambiguous.

If the underlined condition is true, then what value will be returned if the EEPROM cell containing incomplete record (compromised one) is read before any explicit write is done? Will it return recovered value, or unpredictable value?


And does the statement apply to both normal write AND quick write, or only normal write? The quick write chapter in AN11983 describes a different data recovery mechanism which uses "Continue interrupted quick write" Flash command.
