AVR Studio’s interface for setting the ISP frequency.

Fuses (proceed with caution!)

Clicking on the Fuses tab automatically causes the programmer to read the fuse settings of the target AVR. If the

programmer is not connected to the target AVR when you select this tab, AVR Studio displays an error message.

Fuses allow you to configure certain persistent, fundamental aspects of your AVR such as boot flash size, brown-out

detection level, and the clock off of which it should run (e.g. external crystal or internal oscillator). To learn more

about the fuses and what they do, see the datasheet for your specific AVR.

Warning: You can permanently disable your AVR by setting the fuses incorrectly. Only

advanced users who know precisely what they are doing should change the fuse settings!
