Hi, I want to build a simple ATmega16 device with no xtals if possible
and I am confused after reading the ATMega16 data sheet.

1. Do the timer intervals rely on the frequency of the main xtal or do
they somehow automatically change if you change the main xtal.
2. If you have no xtal does this affect the timers much?
3. Will the Timers work if you have no Xtal connected to the TOSCI pins?
4. Does the Xtal frequency affect the serial input baud rate?

Thanks Ted
