Introduction
EEPROM backup data record — The EEPROM backup data record is comprised of a
2-bit status field, a 14-bit address field, and a 16-bit data field found in EEPROM backup
data memory which is used by the EEPROM filing system. If the status field indicates a
record is valid, the data field is mirrored in the FlexRAM at a location determined by the
address field.
EEPROM backup data memory — Partitioned from the FlexNVM block, EEPROM
backup data memory provides nonvolatile storage for the EEPROM filing system
representing data written to the FlexRAM requiring highest endurance.
EEPROM backup data sector — The EEPROM backup data sector contains one
EEPROM backup data header and up to 255 EEPROM backup data records, which are
used by the EEPROM filing system.
Endurance — The number of times that a flash memory location can be erased and
reprogrammed.
FCCOB (Flash Common Command Object) — A group of flash registers that are used
to pass command, address, data, and any associated parameters to the memory controller
in the FTFL module.
Flash block — A macro within the FTFL module which provides the nonvolatile
memory storage.
FlexMemory — FTFL configuration that supports data flash, EEPROM, and FlexRAM.
FlexNVM Block — The FlexNVM block can be configured to be used as data flash
memory, EEPROM backup flash memory, or a combination of both.
FlexRAM — The FlexRAM refers to a RAM, dedicated to the FTFL module, that can be
configured to store EEPROM data or as traditional RAM. When configured for
EEPROM, valid writes to the FlexRAM generate new EEPROM backup data records
stored in the EEPROM backup flash memory.
FTFL Module — All flash blocks plus a flash management unit providing high-level
control and an interface to MCU buses.
IFR — Nonvolatile information register found in each flash block, separate from the
main memory array.
NVM — Nonvolatile memory. A memory technology that maintains stored data during
power-off. The flash array is an NVM using NOR-type flash memory technology.
NVM Normal Mode — An NVM mode that provides basic user access to FTFL
resources. The CPU or other bus masters initiate flash program and erase operations (or
other FTFL commands) using writes to the FCCOB register group in the FTFL module.
