最近在做毕设，要用到stm8l152芯片，可是不知道怎样编写它内部eeprom的读写，解密加密程序，有没有哪位高手知道啊？请不吝赐教。

RE:stm8l的eeprom程序

void Init_EEPROM(void) //FLASH解锁
{
   /*FLASH编程时间定义*/
  FLASH_SetProgrammingTime(FLASH_ProgramTime_Standard);
  /* Unlock flash Data memory */
  FLASH_Unlock(FLASH_MemType_Data);
  /* Wait until Data EEPROM area unlocked flag is set*/
  while (FLASH_GetFlagStatus(FLASH_FLAG_DUL) == RESET)
  {}
}
void __eeprom_write_16(unsigned short addr_eep,unsigned short data) //写一个双字节数据
{
FLASH_WaitForLastOperation(FLASH_MemType_Data);
   FLASH_Unlock(FLASH_MemType_Data);
   FLASH_ProgramByte(addr_eep, data/256);
   FLASH_WaitForLastOperation(FLASH_MemType_Data);
   FLASH_ProgramByte(addr_eep+1, data%256);
   FLASH_WaitForLastOperation(FLASH_MemType_Data);
   FLASH_Lock(FLASH_MemType_Data);
}
s16__eeprom_read_16(unsigned short addr_eep) //读一个双字节数据
{
s16 Save=0;
FLASH_WaitForLastOperation(FLASH_MemType_Data);
FLASH_Unlock(FLASH_MemType_Data);
Save=FLASH_ReadByte(addr_eep);
Save=Save*256;
FLASH_WaitForLastOperation(FLASH_MemType_Data);
Save+=FLASH_ReadByte(addr_eep+1);
FLASH_WaitForLastOperation(FLASH_MemType_Data);
   FLASH_Lock(FLASH_MemType_Data);
return(Save);
}
