I'm using the KE1xF with a FlexNVM size of 64 kByte. I want to partition it with 4 kByte EEPROM data set size and 32 kBytes data flash size.
However, the manual and AN5338 says the EEPROM backup size must be at least 16 times the EEPROM data set size which means the whole FlexNVM size has to be used as EEPROM backup size for the 4 kByte EEPROM data set size.
Where does this restriction come from? Is it only endurance? What happens if I'm partitioning the FlexNVM in the way above?
