I know you don't say that every time someone makes
different assumptions about context than you have.
So for now I guess I'll just feel special...

And I expect you'd have to admit that if indeed there
were some IP reuse happening, then everything I said
which assumed reuse would be true.  Likewise, that
such reuse does happen even for simple stuff like
GPIOs (to facilitate reuse of program code ... even
on  the 8-bit micros you mentioned, I've seen it).
