stm8s,想保存几个字节的数据到flash或者eeprom,改怎么做?

#include "stm8s_conf.h" 



void __eeprom_write_8(unsigned short addr_eep,unsigned char data) 

{ 

  FLASH_WaitForLastOperation(FLASH_MEMTYPE_DATA);   

  FLASH_Unlock(FLASH_MEMTYPE_DATA);

  FLASH_Lock(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);

}
