Ok, just so that we're on the same page, we have two oscillators running
at 32kHz, the internal being always there, and the external that could
or could not be there, and it's each different hardware block that can
be wired to one, the other or both?

There's no global mux that could use either one of the two 32k to
provide the only 32kHz source in the system, right?
