求9S12HY64的D-FLASH读写程序.我写了一个,但是总是被它的地址弄晕,现在擦除0x4400地址,然后写入数据,能擦能写,可是D-FLASH的空间是0x10440开始啊,晕.求助各位帮忙

DFLASH = READ_ONLY 0x010400 TO 0x0113FF;
DFlash_Erase(0x4400);
DFlash_Write(0x4400,Buffer);
执行后写入数据的地址为0x00400,而非0x010400.为什么?

int DFlash_Write(word ADDR16,unsigned int Buffer[])
{

  if(FCLKDIV_FDIVLD ==0)
FCLKDIV_FDIV = 0x07;

  FSTAT_ACCERR = 1;
delay(100);
FSTAT_FPVIOL = 1;

  FCCOBIX_CCOBIX = 0x00;
  FCCOBHI = 0x11;//Program D-Flash Command
  FCCOBLO = 0x00;//0x00;
delayl(100);

  FCCOBIX_CCOBIX = 0x01;
  FCCOB = ADDR16;

  FCCOBIX_CCOBIX = 0x02;  //word0
  FCCOB = Buffer[0];

  FCCOBIX_CCOBIX = 0x03;  //word1
  FCCOB = Buffer[1];

  FCCOBIX_CCOBIX = 0x04;  //word2
  FCCOB = Buffer[2];

  FCCOBIX_CCOBIX = 0x05;  //word3
  FCCOB = Buffer[3];
delayl(100);
  FSTAT_CCIF = 1;//launch command
  while (FSTAT_CCIF == 0);

  if (FSTAT_ACCERR || FSTAT_FPVIOL || FSTAT_MGSTAT)
  {
FSTAT_ACCERR = 1;
FSTAT_FPVIOL = 1;
return -1;
  }

return 1;
}
