11.2 Overview

The NVM Controller (NVMCTRL) is the interface between the CPU and Nonvolatile Memories (Flash, EEPROM, Signature Row, User Row, and fuses). These are reprogrammable memory blocks that retain their values when not powered. The Flash is mainly used for program storage but can also be used for data storage. EEPROM, Signature Row, User Row, and fuses are used solely for data storage.
