Re: [avr-chat] UART with internal RC osc.

[Reza Naima]

At one of the meetings that atmel put on that I went to, I asked the 
developer there in regards to the butterly.  If you're using an external 
clock oscillator, you can use that to calibrate the internal RC every so 
often to compensate for temperature changes.
