I guess "SC" could even more so stand for various things. Even the spelled out "System Control" looks overly generic. If this isn't Arm-specific (in which case adding "arm" into the name might at least help the situation a little), then I guess some further disambiguation is going to be wanted. Since I don't know any of the context of this, I'm afraid you're in a far better position than me to come up with a non-ambiguous name. Jan
