28.1.3 Glossary
Command write sequence — A series of MCU writes to the Flash FCCOB register
group that initiates and controls the execution of Flash algorithms that are built into the
FTFL module.
Data flash memory — Partitioned from the FlexNVM block, the data flash memory
provides nonvolatile storage for user data, boot code, and additional code store.
Data flash sector — The data flash sector is the smallest portion of the data flash
memory that can be erased.
EEPROM — Using a built-in filing system, the FTFL module emulates the
characteristics of an EEPROM by effectively providing a high-endurance, byte-writeable
(program and erase) NVM.
EEPROM backup data header — The EEPROM backup data header is comprised of a
32-bit field found in EEPROM backup data memory which contains information used by
the EEPROM filing system to determine the status of a specific EEPROM backup flash
sector.
