Hello,

I am trying to write value 7 to eeprom data memory area. My code is below..

/* MAIN.C file

 *  * Copyright (c) 2002-2005 STMicroelectronics */

#include 'STM8S003F3P.h'

 unsigned int *ptr=(unsigned int *)0X4000;

 main(){while (1){

if(!(FLASH_IAPSR & (1<<3))){

                                                        FLASH_DUKR=0XAE;                            FLASH_DUKR=0X56;                                                        *ptr++=7;                            FLASH_IAPSR &=~(1<<3);                                                                                                                }}}

But there is no value  written to eeprom. Further please let me  know how to chek  eeprom data in stvd or stvp .
