Hi All: The point is, I'd like to have some memory that doesn't "leave" wit= h lost power, I mean, if I made a change of some memory value (variable) = it remains even though I turn the device off... I guess I=B4m not clear, so I'll try to improve... I.e. I have a device that counts external events, let's say I've al= ready counted 5 (I'm storing that data in a variable) in that moment I turn t= he device off, but next time I want my device to begin counting from 5 to = up... It is possible to do? if the answer is yes, please tell me how... That's why I was thinking of using program memory as data memory...
