Sorry, I disagree. This debug message is actually saying what is
happening when the ref_clock value is *_XTAL and what happens cannot be
seen in this part of the code, only in the part that calls this
function.
In fact, I almost removed this debug message completely, because there
are way too many debug messages that are good during implementation, but
shouldn't go out when the implementation is working.
I'll keep it (for now) after the function is called.

This comment is useless in this part of the code. If it should be
somewhere, it should be where the macros are defined. But even there, I
think it doesn't add any value, because it's so obvious.

Ooops! Good that you noticed, thanks! I'll fix it.
