Adjust the timer on a simulator software

Hello !
I need some help to configure the ATmega328 on ISIS, can you help me ?


(don’t pay attention to the arrow)

Thanks !

Can you help me with my taxes? Especially the part about sending the money?

What does this have to do with the Arduino?

I just remembered that I don't explain how to do. I put an external clock ready-made (or not) on pins XTALS. Very simple, really.
