Dear friends
I want to have a memory location( Non volatile) say "cal" which will only increment when ever there is any change in data in its adjecent (not necessay adjacent) memory location say "factor".
I know its very easy by simply using an EEPROM with some software written in the main controller untill this line is added " Even the designer cannot change cal".
Means this cal is not acceble by the designer. Cal can only be changed (increased)indirectly by updating "factor"
Is there any device available which serves this purpose.
Please help me and Thanx in advance
