I'm wondering. The data sheet of the atmegas tell thatthe maximum speed is 16 mhz.
But at the baudrate section you see a table for 20 mhz.
And some sites sell development board with 20 mhz cristal.
So my question is does the atmega work stable on 20 mhz, any one try it.
And a silly question can the atmega run at 100mhz cooled with liquid nitro or something.
