I want to place presets in the internal eeprom which I can access later on with read_eeprom(), but I found nothing if i can do this and how.
I'm using 16F684.
Does anybody know howto do this?

MPLAB allows you to preset the EEPROM when programming devices.

Or you can preset the locations yourself on boot up by checking for a known "magic" value at a known EEPROM location. If the "magic" value exists, you know that the EEPOMR has already been preset. If no magic value is found, you can load the EEPOMR using write_eeprom().

There are several other threads covering this, so do a search for EEPROM.

You can also use the #ROM directive.

I just found out #ROM 0x2100 works fine!
