Chapter 1 Overview

1.1

Outline

EEPROM emulation is a feature used to store data in the on-board flash memory in the same way as EEPROM.

During EEPROM emulation, the Data Flash library and EEPROM emulation library are used, and the data flash

memory is written to and read from.

The Data Flash library is a software library used to perform operations on the data flash memory. The EEPROM

emulation library is a software library used to execute EEPROM emulation from a user-created program. The Data

Flash library and EEPROM emulation library are placed in the code flash memory for use.

The EEPROM emulation library is free software to rewrite the data flash through the user program.

In this user’s manual, processing of the EEPROM emulation library includes processing of the Data Flash library.

Be sure to use this user’s manual together with the release note supplied with the package of this EEPROM

emulation library and the user’s manual for the target device.
