1. SYS_UnlockReg(); //1. 要先解锁保护寄存器
   
2. FMC_Open();      //2. 打开FMC功能, 后面再进行读写操作
   
3. 
   
4. FMC_Write((uint32_t)&TVTHAVED, 0);//TVTHAVED = 0;
   
5.

FMC_Write((uint32_t)&TVTHAVED,0);//TVTHAVED = 0;


FMC_Open();
                SYS_UnlockReg();
                int16_t tmp;
    uint8_t i=0;
    int8_t j=0;
    TVT_Haved =FMC_Read( (uint32_t)&TVTHAVED);

读出来都是255 ' ',没加FMC_Open();时读出来都是65.
