Very true indeed. It was nice hearing a sine wave come out....even if it was
not ready for prime time.
You may need to adjust the RCMR, RFRM, TCMR, TFRM register settings in

I will do this. I can probe the clock and data lines to make sure they are
looking like what I expect and then look to the modes to see what I need to
change in the directories.

I will give this conf a whirl and see what it does.
Thanks.
