I'm not sure what code you're looking at, but I'm going to guess that you're a little confused about the difference between applying the static keyword to a function versus to a variable... an unfortunate overloading of the term in C... static functions are very different than static variables. When applied to a function, it makes sure the function is not visible outside the file in which it's implemented. That's all. When applied to a variable, however, it essentially turns the variable into a global variable, but not visible outside the file or function in which its defined (the compiler access it as an offset from the A5 register rather than the SP register). It is therefore only "available" during launch codes which provide global variable storage. Hope that clears things up a bit...
