For some strange reason I am unable to write values to the EEPROM on my PIC16f628a at program time. This is fine after the first time the program runs as it reads and writes a particular value each time the code loops.
I would like to be able to know if the eeprom has been programmed or not.
My question is:
How can I test the eeprom value at run time to see if it has been programmed?
In otherwords what does an unprogrammed eeprom address read as?
Thanks
John
