Notes:

  1. For the EEPROM emulation library, contact your local Renesas Electronics marketing office or distributor.
  2. In the User's Manual (Hardware) for some RL78 MCUs or the User's Manual for some Flash Libraries for the RL78 family, the self RAM areas used in common for all flash libraries may be shown. However, for the latest information, please refer to the RL78 Family Self RAM list of Flash Self Programming Library Rev.3.05 (PDF | English, 日本語).
  3. As the self RAM areas are used as the work area for the library, using these areas for the user program is prohibited. For the latest information, please refer to the RL78 Family Self RAM list of Flash Self Programming Library Rev.3.05 (PDF | English, 日本語).
