EEESIZE
EEPROM Size — Encoding of the total available FlexRAM for EEPROM use.
NOTE: EEESIZE must be 0 bytes (1111b) when the FlexNVM partition code (FlexNVM Partition
Code) is set to 'No EEPROM'.

28.3.3.2 FlexNVM Partition Code
The FlexNVM Partition Code byte in the data flash IFR supplies a code which specifies
how to split the FlexNVM block between data flash memory and EEPROM backup
memory supporting EEPROM functions. To program the DEPART value, see the
Program Partition command described in Program Partition Command.
