写了段Eeprom的程序

能写进去擦除不了

程序如下

unsigned char EepromErase(unsigned char size)
{
  unsigned int *pAddress;
  while(!(ECLKDIV & 0x80));
  while(!(ESTAT & 0x80));
  while(!(EPROT & 0x80));
  pAddress=(unsigned int*)(0x2000);
  if(ECLKDIV_EDIVLD == 1)
  {
    if((ESTAT_ACCERR == 0) && (ESTAT_PVIOL == 0))
    {
      while(size)
      {
        if(ESTAT_CBEIF == 1)
        {
          ECMD =0x40;
          ESTAT_CBEIF = 1;
          pAddress += 2;
          if((ESTAT_ACCERR == 1) || (ESTAT_PVIOL == 1))
          {
            return 1;
            break;
          }
          while (ESTAT_CCIF == 0);
          size--;
        }
       }
       return 0;
      }
      else return 1;
   }
   else return 1;
}

没有报错

我分配的Eeprom空间从2000到27ff

请各位大侠指教
