No, that's a good comment, I'll change that.

I wrote this incrementaly, first the node, then the opp-hz. Then I realized that
the source crystal, at 3.8684 MHz didn't provide a round 99.5 MHz core clock,
but a 99.5328 MHz clock.

Anyway, I'll change that ... let's say into opp at 99533 in this case ?
