Setting the Enable Partitioning checkbox enables you to partition your Kinetis chip. To setup partitioning, you must provide two bytes in hexadecimal format. The first byte represents the EEPROM Data Set Size, which determines the amount of FlexRAM used in each of the available EEPROM subsystems. This byte must be in the range of 0x00 to 0x3F. The second byte represents the FlexNVM Partition Code, which specifies how to split the FlexNVM block between data flash and EEPROM backup memory supporting EEPROM functions. This must be in the range of 0x00 to 0x0E. Refer to the reference manual specific to the device you are working with for more information on how to specify the EEPROM Data Set Size and FlexNVM Partition Code.
