Security
The device will make available a security feature preventing the unauthorized read and write of the memory contents. This feature allows:
- Protection of the contents of FLASH,
- Protection of the contents of EEPROM,
- Operation in single-chip mode,
- Operation from external memory with internal FLASH and EEPROM disabled.
