最近偶尔用到408as 的EEPROM，找了一点历程是stc89c52的，完全可以用，
能保存多组433遥控码，也可以清除一保存的遥控码，现在打算移植到108as
上面来，无奈怎么做都不可以，就我知道的，我该改的都改了，还是不行，有没有哪位可以帮帮我

下面是stc89c52原eesprom程序

void EEPROM_write(uchar address, uchar value)//写EEPROM
{
xdata uchar da[255];
  uchar x;

  for(x=0;x<255;x++)
  da[x] = EEPROM_read(x);//读EEPROM

  da[address] = value;

  IapEraseSector(0X2000);

  for(x=0;x<255;x++)
  IapProgramByte(x+0x2000,da[x]);
}

uchar EEPROM_read(uchar address)//读EEPROM
{
  uchar da;
  da=IapReadByte(address+0x2000);
return da;
}
//关闭IAP
void IapIdle()
{
IAP_CONTR = 0;                //Close IAP function
IAP_CMD = 0;                   //Clear command to standby
IAP_TRIG = 0;                //Clear trigger register
IAP_ADDRH = 0x80;             //Data ptr point to non-EEPROM area
IAP_ADDRL = 0;                //Clear IAP address to prevent misuse
}
读一字节，调用前需打开IAP 功能
BYTE IapReadByte(WORD addr)
{
BYTE dat;                      //Data buffer
IAP_CONTR = ENABLE_IAP;       //Open IAP function, and set wait time
IAP_CMD = CMD_READ;          //Set ISP/IAP/EEPROM READ command
IAP_ADDRL = addr;             //Set ISP/IAP/EEPROM address low
IAP_ADDRH = addr >> 8;       //Set ISP/IAP/EEPROM address high
IAP_TRIG = 0x46;             //Send trigger command1 (0x46)
IAP_TRIG = 0xb9;             //Send trigger command2 (0xb9)
_nop_();                      //MCU will hold here until ISP/IAP/EEPROM operation complete
dat = IAP_DATA;                //Read ISP/IAP/EEPROM data
IapIdle();                   //Close ISP/IAP/EEPROM function

return dat;                   //Return Flash data
}
//字节编程
void IapProgramByte(WORD addr, BYTE dat)
{
IAP_CONTR = ENABLE_IAP;       //Open IAP function, and set wait time
IAP_CMD = CMD_PROGRAM;       //Set ISP/IAP/EEPROM PROGRAM command
IAP_ADDRL = addr;             //Set ISP/IAP/EEPROM address low
IAP_ADDRH = addr >> 8;       //Set ISP/IAP/EEPROM address high
IAP_DATA = dat;                //Write ISP/IAP/EEPROM data
IAP_TRIG = 0x46;             //Send trigger command1 (0x46)
IAP_TRIG = 0xb9;             //Send trigger command2 (0xb9)
_nop_();                      //MCU will hold here until ISP/IAP/EEPROM operation complete
IapIdle();
}
//擦除扇区,
void IapEraseSector(WORD addr)
{
IAP_CONTR = ENABLE_IAP;       //Open IAP function, and set wait time
IAP_CMD = CMD_ERASE;          //Set ISP/IAP/EEPROM ERASE command
IAP_ADDRL = addr;             //Set ISP/IAP/EEPROM address low
IAP_ADDRH = addr >> 8;       //Set ISP/IAP/EEPROM address high
IAP_TRIG = 0x46;             //Send trigger command1 (0x46)
IAP_TRIG = 0xb9;             //Send trigger command2 (0xb9)
_nop_();                      //MCU will hold here until ISP/IAP/EEPROM operation complete
IapIdle();
}

下面是写入数据代码

if(rf_ok)
{
GIE=0;
num_rf=EEPROM_read(0x00);    //取已学习的遥控器数量
if(num_rf>40){num_rf=0;}       //如果遥控器数量超过40个，覆盖最先学习的

EEPROM_write(0,num_rf+1);

         EEPROM_write(num_rf*3+1,mma1);
EEPROM_write(num_rf*3+2,mma2);
EEPROM_write(num_rf*3+3,mma3);
LED=0;
delay_ms(200);//200
LED=1;
rf_ok=0;

GIE=1;

   }

下面是我子去官网弄的408的EEPROM代码

/*----------------------------
关闭IAP
----------------------------*/
void IapIdle()
{
IAP_CONTR = 0; //关闭IAP功能
IAP_CMD = 0; //清除命令寄存器
IAP_TRIG = 0; //清除触发寄存器
IAP_ADDRH = 0x80; //将地址设置到非IAP区域
IAP_ADDRL = 0;
}
/*----------------------------
从ISP/IAP/EEPROM区域读取一字节
----------------------------*/
BYTE IapReadByte(WORD addr)
{
BYTE dat; //数据缓冲区
IAP_CONTR = ENABLE_IAP; //使能IAP
IAP_CMD = CMD_READ; //设置IAP命令
IAP_ADDRL = addr; //设置IAP低地址
IAP_ADDRH = addr >> 8; //设置IAP高地址
IAP_TRIG = 0x5a; //写触发命令(0x5a)
IAP_TRIG = 0xa5; //写触发命令(0xa5)
_nop_(); //等待ISP/IAP/EEPROM操作完成
dat = IAP_DATA; //读ISP/IAP/EEPROM数据
IapIdle(); //关闭IAP功能
return dat; //返回

}

/*----------------------------
写一字节数据到ISP/IAP/EEPROM区域
----------------------------*/
void IapProgramByte(WORD addr, BYTE dat)
{
IAP_CONTR = ENABLE_IAP; //使能IAP
IAP_CMD = CMD_PROGRAM; //设置IAP命令
IAP_ADDRL = addr; //设置IAP低地址
IAP_ADDRH = addr >> 8; //设置IAP高地址
IAP_DATA = dat; //写ISP/IAP/EEPROM数据
IAP_TRIG = 0x5a; //写触发命令(0x5a)
IAP_TRIG = 0xa5; //写触发命令(0xa5)
_nop_(); //等待ISP/IAP/EEPROM操作完成
IapIdle();
}
/*----------------------------
扇区擦除
----------------------------*/
void IapEraseSector(WORD addr)
{
IAP_CONTR = ENABLE_IAP; //使能IAP
IAP_CMD = CMD_ERASE; //设置IAP命令
IAP_ADDRL = addr; //设置IAP低地址
IAP_ADDRH = addr >> 8; //设置IAP高地址
IAP_TRIG = 0x5a; //写触发命令(0x5a)
IAP_TRIG = 0xa5; //写触发命令(0xa5)
_nop_(); //等待ISP/IAP/EEPROM操作完成
IapIdle();
}
其实，我也就只知道改了0x5a和基本的头文件

哎，由于水平太烂了，搞不定，所以出来请教
