I found some old code in ggsound that apparently does nothing to the sweep unit but set the negate flag. Removing all the code which references and uploads this register results in unchanged behavior. I can't remember why I have it in the codebase, except that it must have been something from MetalSlime's original audio tutorial from which I originally learned.
What is the behavior of the sweep unit if you do absolutely nothing to it from startup, or is it advised to at least set it to some nominal value?
