After clearing CCIF to launch the Program Partition command, the FTFL first verifies
that the EEPROM Data Size Code and FlexNVM Partition Code in the data flash IFR are
erased. If erased, the Program Partition command erases the contents of the FlexNVM
memory. If the FlexNVM is to be partitioned for EEPROM backup, the allocated
EEPROM backup sectors are formatted for EEPROM use. Finally, the partition codes are
programmed into the data flash IFR using the values provided. The Program Partition
command also verifies that the partition codes read back correctly after programming. If
the FlexNVM is partitioned for EEPROM, the allocated EEPROM backup sectors are
formatted for EEPROM use. The CCIF flag is set after the Program Partition operation
completes.
Prior to launching the Program Partition command, the data flash IFR must be in an
erased state, which can be accomplished by executing the Erase All Blocks command or
by an external request (see Erase All Blocks Command). The EEPROM Data Size Code
and FlexNVM Partition Code are read using the Read Resource command (see Read
Resource Command).

Error Condition
Command not available in current mode/security
The EEPROM data size and FlexNVM partition code bytes are not initially 0xFFFF
Invalid EEPROM Data Size Code is entered (see Table 28-70 for valid codes)
Invalid FlexNVM Partition Code is entered (see Table 28-71 for valid codes)
FlexNVM Partition Code = full data flash (no EEPROM) and EEPROM Data Size Code
allocates FlexRAM for EEPROM
