hi Peter,
Now, all I have to do if figure out where is 3. I chose location 3 at random.
whatever the location you choose, it refer to a specific location of the INTERNAL EEPROM. So, 0 is the first location of the EEPROM. It's a separate location of your codespace. If you'r using MPLAB, you can read PROGRAM MEMORY, EEPROM.

You can maybe consider EEPROM as an other internal register... only to figure out.
