8.1.5.2.1 Secure Embedded Flash Controller (SEFC)

The Secure Embedded Flash Controller (SEFC) manages accesses performed by hosts of the system. It enables reading the Flash and writing the write buffer. It also contains a user interface, mapped on the APB.

The SEFC ensures the interface of the Flash block. It manages the programming, erasing, locking and unlocking sequences of the Flash using the full set of commands.

For dual-plane devices, each plane is managed by an SEFC. Flash Wait State and Flash Optimization mode must be set up in both SEFCs.
