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.
