9.2 Overview

The NVM Controller (NVMCTRL) is the interface between the device, the Flash, and the EEPROM. The Flash and EEPROM are reprogrammable memory blocks that retain their values even when not powered. The Flash is mainly used for program storage and can be used for data storage. The EEPROM is used for data storage and can be programmed while the CPU is running the program from the Flash.
