Re: [uracoli-devel] Baud rates

[Vasilakes, Keith]

Because if I see 'calibrate' I think I'm expecting the osc freq to be fixed to 
the design value.
So it should be calibrated to 8mhz because that's the frequency that the device 
is supposed to run at.

Adjusting the frequency allows for making the osc freq something other than the 
designed freq...

It's a small semantic issue I know.

Why?  Just calibrating it to whatever F_CPU has been set seems to
be a reasonably good idea to me.

Of course, any actual implementation might impose restrictions on
the possible F_CPU values it is willing to calibrate against.
