	The steps vary Bob, what seems to be happening is the PLL is getting
programmed by the MCU but the incremental updates provided by the DAC which
shifts the reference osc around does not seem to be there. I was hoping to
find a logic probe at the local emporiums of electronic parts, but none have
one. I see the effect of what I think is going on, but difficult to trouble
shoot because the cause just isn't there very long, ie signals SCO, SCK and
DAC2SEL.
