调用存储数据第一次存储（FLASH数据FF状态）数据正常，再次存储无法把FLASH正确擦除，ErasePage擦除函数返回状态2（写保护错误），函数如下。

void EEPROM_SaveInFlash (uint16 job, uint8 En)
{
uint8 ID,Number;

if (En == DEF_ENABLED )  {                            // ÄÚ²¿FLASH´¦Àí
   FLASH_Unlock();                                  // FLASH½âËø

   /* Clear All pending flags */
   FLASH_ClearFlag(FLASH_FLAG_BSY | FLASH_FLAG_PRCDN|FLASH_FLAG_PRGMFLR |FLASH_FLAG_WRPRTFLR);
   FlashStatus = FLASH_ErasePage(EEPROM_START_ADDRESS);

   WeldBuffer[0][0] = 300;
   WeldBuffer[0][1] = 154;
   WeldBuffer[0][2] = Job_Data.MemorySetNub;
   WeldBuffer[0][3] = Job_Data.MIGSetVoltageCorrect;
   WeldBuffer[0][4] = Job_Data.MIGSetMotorSpeedCorrect;
   WeldBuffer[0][5] = Job_Data.MIGSetCurrentCorrect;
   WeldBuffer[0][6] = Job_Data.MIGDisCurrentCorrect;
   WeldBuffer[0][7] = Job_Data.K;
   WeldBuffer[0][8] = Job_Data.B;
   WeldBuffer[0][9] = Job_Data.TestCount;
         WeldBuffer[0][10] = Job_Data.TIG200_220_Fg;
         WeldBuffer[0][11] = Job_Data.MIGDisACVoltageCorrect;

   for (ID = 0; ID < 61; ID++)  {
      for (Number = 0; (Number < 150) && (FlashStatus == FLASH_PRC_DONE); Number++)  {
   FlashStatus = FLASH_ProgramHalfWord((EEPROM_START_ADDRESS + (((ID * 150) + Number) * 2)), WeldBuffer[ID][Number]);
      }
   }
FLASH_Lock();                            // FLASHÉÏËø
} else {                               // ½ö½öÄÚ²¿RAM½»»»
   for (Number = 0; Number < 150; Number++)
         WeldBuffer[job][Number] = WeldBuffer[0][Number];
}

}
