IAR编译报错 value of type "u8 (*)(u32, u8 *)" cannot be assigned to an entity

UINT8 FAT32_ReadSector(UINT32 addr,UINT8 *buf)
{
switch(Dev_No)
{
  case SDCARD:
         pRS=SD_ReadSingleBlock;  //pRS=SD_Read_Sector;
         break;
  case UDISK:
         //pRS=CH375_Read_Sector;
         break;
  case CFCARD:
         //pRS=CF_Read_Sector;
         //无
         break;
  case OTHER:
         //无
         break;
}
return (*pRS)(addr,buf);  //替换成实际存储器的扇区读函数，这里是SD卡扇区读函数
//return  SD_ReadSingleBlock(addr,buf);  //替换成实际存储器的扇区读函数，这里是SD卡扇区读函数
}
为什么这段程序在Keil编译通过工作正常，在IAR中编译报错呢？
报错显示：Error[Pe513]: a value of type "u8 (*)(u32, u8 *)" cannot be assigned to an entity of  C:\Documents and Settings\Administrator\桌面\IAR_SD卡\znFAT.c 63   。各位高手指点一下啊。
