Backup Library User's Manual

1. Guide

1.1 Purpose

This game machine will be equipped with several types of storage devices including internal memory to store information during the game.
This library provides read / write and search functions for these backup storage devices.

1.2 Description

1.2.1 Introduction

Be sure to use this library to access the backup storage device.

1.2.2 How to use the library

The main body of this library is compressed and stored in the BOOT ROM.
∙ Application creator will deploy and use it. Expansion is performed by securing the program expansion area and executing BUP_Init (). After that, each function can be used.

1.2.3 Storage capacity

The purpose of this library is to be able to access future supported devices with a common interface. Therefore, the capacity of the storage device to be developed in the future is unknown. Some devices are divided into several sections. In the following, one delimited unit is called a partition. (The capacity of each partition may vary.)
* When storing data, execute BUP_SelPart () and BUP_Stat () to check the capacity before writing.
* The internal backup memory is 32K.

1.2.4 Date setting

This library does not have a date / time acquisition function to maintain the independence of the library. For date / time data, set the data obtained on the application side using BUP_SetDate ().

1.2.5 Notes

If this library is interrupted while writing data, the data will be destroyed. Before executing BUP_Init (), BUP_Format (), BUP_Write (), or BUP_Delete (), use PER_SMPC_RES_DIS () in the system library to disable the reset button.
