Table 28-4. FlexNVM Partition Code Field Description
Field Description
7-4
Reserved
This read-only bitfield is reserved and must always be written as one.
3-0
DEPART
FlexNVM Partition Code — Encoding of the data flash / EEPROM backup split within the FlexNVM
memory block. FlexNVM memory not partitioned for data flash will be used to store EEPROM
records.
0000 = 32 Kbytes of data flash, No EEPROM backup (No EEPROM)
0001 = 24 Kbytes of data flash, 8 Kbytes of EEPROM backup
0010 = 16 Kbytes of data flash, 16 Kbytes of EEPROM backup
0011 = No data flash, 32 Kbytes of EEPROM backup
0100 = Reserved
0101 = Reserved
0110 = Reserved
0111 = Reserved
1000 = No data flash, 32 Kbytes of EEPROM backup
1001 = 8 Kbytes of data flash, 24 Kbytes of EEPROM backup
1010 = 16 Kbytes of data flash, 16 Kbytes of EEPROM backup
1011 = 32 Kbytes of data flash, No EEPROM backup (No EEPROM)
1100 = Reserved
1101 = Reserved
1110 = Reserved
1111 = Reserved (defaults to 32 Kbytes of data flash, No EEPROM)
28.3.4 Register Descriptions
The flash memory module contains a set of memory-mapped control and status registers.
NOTE
While a command is running (FSTAT[CCIF]=0), register
writes are not accepted to any register except FCNFG and
FSTAT. The no-write rule is relaxed during the start-up reset
sequence, prior to the initial rise of CCIF. During this
initialization period the user may write any register. All register
writes are also disabled (except for registers FCNFG and
FSTAT) whenever an erase suspend request is active
(FCNFG[ERSSUSP]=1).
