Enable_Write_Flash();
FMC_ReadUID(0,&uid);
Disable_Write_Flash();

int32_t FMC_ReadUID(int index, uint32_t * u32data)
{
FMC->u32ISPCMD = 0x4;

FMC->ISPADR = 0x04 * index;

FMC->ISPTRG.ISPGO = 1;
while (FMC->ISPTRG.ISPGO);
if (FMC->ISPCON.ISPFF == 1)
{
FMC->ISPCON.ISPFF = 1;
}

*u32data = FMC->ISPDAT;

return 0;
}

Enable_Write_Flash();
FMC_ReadUID(0,&uid0);
FMC_ReadUID(0,&uid1);
FMC_ReadUID(0,&uid2);
Disable_Write_Flash();

每次读一个字,32位,读三次.

请到新唐主页下载MINI51的BSP包，里面有详细例子如何读UID，UCID等。

附带我的学习笔记
int32_t DrvFMC_Read_UID(uint32_t u32addr, uint32_t * u32data)
{
FMC->ISPCMD.FCTRL = 4; //命令字
FMC->ISPCMD.FCEN = 0;
FMC->ISPCMD.FOEN = 0;

FMC->ISPADR = u32addr;

FMC->ISPDAT = 0;
FMC->ISPTRG.ISPGO = 1;
__ISB();
while (FMC->ISPTRG.ISPGO);

if (FMC->ISPCON.ISPFF == 1)
{
FMC->ISPCON.ISPFF = 1;
return E_DRVFMC_ERR_ISP_FAIL;
}

*u32data = FMC->ISPDAT;
return 0;
}

DrvFMC_Read_UID(0x0, &data);
datax[0]=data;
DrvFMC_Read_UID(0x4, &data);
datax[1]=data;
DrvFMC_Read_UID(0x8, &data);
datax[2]=data;
