Table 28-2. EEPROM Data Set Size Field Description
Description
This read-only bitfield is reserved and must always be written as one.
EEPROM Split Factor — Determines the relative sizes of the two EEPROM subsystems.
‘00’ = Subsystem A: EEESIZE*1/8, subsystem B: EEESIZE*7/8
‘01’ = Subsystem A: EEESIZE*1/4, subsystem B: EEESIZE*3/4
‘10’ = Subsystem A: EEESIZE*1/2, subsystem B: EEESIZE*1/2
‘11’ = Subsystem A: EEESIZE*1/2, subsystem B: EEESIZE*1/2
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.
