Field
Description
For program flash only configurations, the SWAP flag indicates which physical program flash block is
located at relative address 0x0000. The state of the SWAP flag is set by the FTFL during the reset
sequence . See the Swap Control command section for information on swap management.

PFLSH
1
RAMRDY
0 Physical program flash 0 is located at relative address 0x0000
1 If the PFLSH flag is set, physical program flash 1 is located at relative address 0x0000. If the PFLSH
flag is not set, physical program flash 0 is located at relative address 0x0000
FTFL configuration
0 For devices with FlexNVM: FTFL configured for FlexMemory that supports data flash and/or
EEPROM For devices with program flash only: Reserved
1 For devices with FlexNVM: Reserved For devices with program flash only: FTFL configured for
program flash only, without support for data flash and/or EEPROM
RAM Ready
This flag indicates the current status of the FlexRAM /programming acceleration RAM .
For devices with FlexNVM: The state of the RAMRDY flag is normally controlled by the Set FlexRAM
Function command. During the reset sequence, the RAMRDY flag is cleared if the FlexNVM block is
partitioned for EEPROM and is set if the FlexNVM block is not partitioned for EEPROM. The RAMRDY
flag is cleared if the Program Partition command is run to partition the FlexNVM block for EEPROM. The
RAMRDY flag sets after completion of the Erase All Blocks command or execution of the erase-all
operation triggered external to the FTFL .
For devices without FlexNVM: This bit should always be set.
0
EEERDY
0 For devices with FlexNVM: FlexRAM is not available for traditional RAM access. For devices without
FlexNVM: Programming acceleration RAM is not available.
1 For devices with FlexNVM: FlexRAM is available as traditional RAM only; writes to the FlexRAM do
not trigger EEPROM operations. For devices without FlexNVM: Programming acceleration RAM is
available.
For devices with FlexNVM: This flag indicates if the EEPROM backup data has been copied to the
FlexRAM and is therefore available for read access.
For devices without FlexNVM: This field is reserved.
0 For devices with FlexNVM: FlexRAM is not available for EEPROM operation.
1 For devices with FlexNVM: FlexRAM is available for EEPROM operations where:
• reads from the FlexRAM return data previously written to the FlexRAM in EEPROM mode and
• writes to the FlexRAM clear EEERDY and launch an EEPROM operation to store the written
data in the FlexRAM and EEPROM backup.
28.34.3 Flash Security Register (FTFL_FSEC)
This read-only register holds all bits associated with the security of the MCU and FTFL
module.
During the reset sequence, the register is loaded with the contents of the flash security
byte in the Flash Configuration Field located in program flash memory. The Flash basis
for the values is signified by X in the reset value.
