Let's say a variable is declared as "var x". Let's assume it occupies dynamic memory, i.e., SD RAM (Synchronous Dynamic RAM). If we never use that variable in real time, how can we save the memory occupied by that variable?
(Meaning of never use in real time is,assume that there is a variables Y and Z,from the external ports if we get inputs,say Y or Z,it is random that either Y has value or Z has value but we have memory can accommodate only one variable's space ,how can we do that?)
