RE: PLL in PCI mode.



Neal,

Do you actually know of any commercial systems that allow the clock to be
stopped on the PCI bus?

Some of the early PCI bus systems were able to change the PCI bus speed
between 25 and 33 MHz...but I haven't seen one able to do that for a
while...and I certainly have never seen one that stops the PCI clock...at
least when the power switch is on, and it's working right ;-)

Regards,

Austin
