[求助] 51單片機配合使用AT24C128B EEPROM程式修改

以上是參考教材中的程式，使用的EEPROM是AT24C02。但現在我手里的單片機開發板使用的EEPROM是AT24C128B，不知如何根據以上程式修改？
WORD ADDRESS我可以寫到哪個位置？
這兩個EEPROM有如下差異：
AT24C02，Byte Write时只有一个WORD ADDRESS，而AT24C128B有两个WORD ADDRESS

恩  对的

哪位大俠能幫幫忙，謝謝啦！

void write_add(uint address,uchar date)
{
start();
write_byte(0xa0);
respons();
write_byte((address>>8)&0xff);
respons();
write_byte((address)&0xff);
respons();
write_byte(date);
respons();
stop();
}

void write_add(uint address,uchar date)
{
        start();
        write_byte(0xa0);
        respons();
        write_byte(address/256);
        respons();
        write_byte(address%256);
        respons();
        write_byte(date);
        respons();
        stop();
}

uchar read_add(uint address)
{
        uchar date;
        start();
        write_byte(0xa0);
        respons();
        write_byte(address/256);
        respons();
        write_byte(address%256);
        respons();
        start();
        write_byte(0xa1);
        respons();
        date=read_byte();
        stop();
        return date;
}
我是這樣寫的，不知道對不對？

感謝，已調試OK。
