Write and Read from internal Memory

[mister_e]

Make sure your PIC programmer program the EEPROM location, unless.. you may read an empty EEPROM $FFFF

Now depending of how you wrote your DATA line, this may work.. or not.

data  @0, WORD 9999

should work.

Your PICProgrammer software should allow to see the EEPROM section, just compile your code, import the .HEX and look if your data is saved in the EEPROM.
