I'm not sure if we're still talking about the same thing or same table;
In any case, this is something up to personal taste in the end, and I am
in the camp that favors (readable, which of course could always be
improved) defines over magic values; especially when it comes to these
bit-selectors. And even if a little less here, to keep things consistent
with all defines is why at least I prefer the one approach. You guys
prefer the raw values. Two flavors of two opinions I suppose :)
