Some basic multimeter questions -- not usage--but design
Ok, Say I would like to make a simple multimeter, maybe just voltmeter at first, with the ATMEGA8, which can take up to 5V. How would I make my voltmeter to measure even 24V...

What does "rjump ." mean?
I see the assembly instruction "rjmp ." with a dot '.' after the 'rjmp'. Does this mean it simply like a no-op jump but takes two cycles?
