Hello all,

What is the proper data type for a pointer to point to, when accessing the EEPROM memory of the AT89S8253 device?
Any help I will appreciate!

Thanks,
Marove

EEPROM is accessible in the XDATA area. For example:
{
unsigned char xdata *pEEPROM;

pEEPROM = (unsigned char xdata *) 0x100;
counter += *pEEPROM; //read EEPROM
//writing EEPROM is more complex, because you have to manage the associated SFRs.
}
