    I have interfaced serial EEPROM with AT89S52. Can I use serial EEPROMs for storing data instead of storing opcodes/programs? And can I use it as FLASH MEMORY for write and erase data at any time? What are the changes to be made and what are the status of WR(bar), RD(bar), ALE, PSEN(bar) pins. Please give me the information. Thank you.
