Grundbeschaltungs von anderen AVR's ansehe... Was heißt hier "andere AVRs"? Bei den alten AVRs der AT90S...-Reihe war es noch erforderlich, eine externe Referenz einzuspeisen, da diese keine interne Einstellmöglichkeit hatten. Da wurde dann meist AVCC eingespeist, wenn z.B. ein Poti angeschlossen werden sollte. Die aktuellen AVRs (ATMega, ATTiny, AT90PWM...) haben alle die Möglichkeit, intern mehrere Referenzquellen auszuwählen, u.a. AVCC. Der Pin sollte bei diesen µCs nur dann mit etwas anderem als einem C gegen GND beschaltet werden, wenn eine
