What kind of data are stored in data memory and what happens if there are lost?
I have only a program memory backup , so i am not sure if the restore procedure is reliable and fully functional.
Same question for option byte....
I wonder if there are available versions of TSDZ2 VLCD-5 firmware files newer than these
