The Device Programming window (also known as the programming dialog), gives you the most low-level control over the debugging and programming tools. Verification errors will occur if the values are read back with undefined bits set to '0'. Now the Atmega chips may have fuses that can be reset, but the concept is the same. You would need to connect a resistor and a capacitor as shown in app note AVR051:. "Checked" means "burn the fuse". For instance, to set default fuse settings, plus disable the ATmega103 compatibility mode use the following: So I have decided to use external 12MHz oscillator crystal and connect them to XTAL1 (pin 9) and XTAL2(pin 10) with 22pF capacitors (ceramic).
