• Normal and Emulation Operating Modes:
  • Normal Single-Chip Mode (Default and used by WTTV)
  • Normal Expanded Wide Mode
  • Normal Expanded Narrow Mode
  • Emulation Expanded Wide Mode
  • Emulation Expanded Narrow Mode
• Special Operating Modes:
  • Special Single-Chip Mode with active Background Debug Mode (Highly interesting for us!)

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.
