Overview

Description

Features

  • Data Flash Libraries provide the interface for operations on the areas of data flash memories that MCUs have. (Functions are supported varies with the MCU. Please check the available functions in the user's manual for the target flash reprogramming software.) :
    • Erasing
    • Programming
    • Internal verification
    • Blank checking, etc.
  • An EEPROM emulation library for data flash memory is also included.

Notes:

  1. 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)".
  2. Because 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)".
