Sorry but i want to ask some questions about calibration feature for internal RC oscillator (Atmega32 MC)
why we must do calibration for each frequency selected (2,4,8 MHZ)??
i read the calibration part in the data sheet but can't understand why we do that?
and if i want to choose an internal freq of 8MHZ how i can calibrate it with the correct value to osccal register??
Thanks in advance,..
