Jamie,

Hold on a second...

1. The default code that IFI provides us works. If we modify it and break it, it can not be their fault. We must assume responsibility for our actions.

2. Just what is the value of an uninitialized variable? Answer: It is undefined. If you are lucky, it will be 0x0000 or 0xFFFF. If you are unlucky, it can be anything.

My point here is that it is impossible to do what you suggest in an embedded controller.

It is possible in a program running under an operating system (the operating system guarantees the starting state of RAM).
