EEPROM memory - ydexter - Jan 25 7:32:00 2003

Hello!

Let's say I want to execute the program inside PIC depending on some
start values, preseted and don't erased at power down. I suppose I
have no option just using that PIC EEPROM.
Question: can this EEPROM be writed by an application outside the PIC
(how?), or the PIC running programm is the only one who can programm
EEPROM?

Thanks

Unfortunately _only_ the program being runned by PIC can write the
PIC internal data eeprom.
But if you want external application to write something to internal
data eeprom you can consider _comunicate_ your external app with
the pic's program, perhaps in a serial way, or something like that.
