本人求助，我使用的是CC2530F256 ZigBee的单片机，因为需要读字库芯片 GT21L16S2W ,而给字库芯片发送的地址是24位的地址需要用长整型 unsigned long 类型；但是IAR编译器能正常编译通过，又是按照unsigned int 类型在跑。而且也无法有bit 位的定义为什么IAR编译器只能到达16位而不能达到32位  本人用的是CD-EW8051-8101  51 版本编译器

如下程序：
#define  SI P0_4
#define  CLK  P0_5
#define  SO P0_6
#define  CS P0_7

#define CS_L       do {CS = 0;}while(0)
#define CS_H       do {CS = 1;}while(0)
#define SI_L       do {SI = 0;}while(0)
#define SI_H       do {SI = 1;}while(0)
#define CLK_L       do {CLK= 0;}while(0)
#define CLK_H       do {CLK= 1;}while(0)

P0SEL &= ~0x10;  // P0_4
      P0DIR |= 0x10;
      P0INP &= ~0x10;

P0SEL &= ~0x20;  // P0_5 sck
      P0DIR |= 0x20;
      P0INP &= ~0x20;

P0SEL &= ~0x40;  // P0_6 输入
      P0DIR &= ~0x40;
      P0INP &= ~0x40;

P0SEL &= ~0x80;  // P0_7 cs
      P0DIR |= 0x80;
      P0INP &= ~0x80;

void SendByte(uint32 cmd)
{
      unsigned char i;
      cmd=cmd|0x03000000;
      for(i=0;i<32;i++)
      {
            CLK_L;
            if(cmd&0x80000000)
                     SI_H;
            else
                     SI_L;
            CLK_H;
            cmd=cmd<<1;
      }
}

unsigned char ReadByte(void)
{
      unsigned char i;
      unsigned char dat=0;
      CLK_H;
      for(i=0;i<8;i++)
      {
            CLK_L;
            dat=dat<<1;
            if(SO)
                     dat=dat|0x01;
            else
                     dat&=0xfe;
            CLK_H       ;
      }
      return dat;
}

unsigned char r_dat_bat(uint32 address,unsigned char byte_long,unsigned char *p_arr)
{
      unsigned int j=0;
      CS_L;
      SendByte(address);
      for(j=0;j<byte_long;j++)
      {
      p_arr[j]=ReadByte();
      }
      CS_H;
      return p_arr[0];
}

void gt_16_GetData (unsigned char MSB, unsigned char LSB, unsigned char* DZ_Data)
{
uint32 BaseAdd=0,Address;
if(MSB == 0xA9 && LSB >=0xA1)
Address = (282 + (LSB - 0xA1))*32+BaseAdd;
else if(MSB >=0xA1 && MSB <= 0xA3 && LSB >=0xA1)
   Address =( (MSB - 0xA1) * 94 + (LSB - 0xA1))*32+ BaseAdd;
else if(MSB >=0xB0 && MSB <= 0xF7 && LSB >=0xA1)
      Address = ((MSB - 0xB0) * 94 + (LSB - 0xA1)+ 846)*32+ BaseAdd;
r_dat_bat(Address,32,DZ_Data);
}

gt_16_GetData(0xC7,0xE9,WZ_Data);

注：0xC7,0xE9 是内码  WZ_Data保存32字节的点阵
