Atmel Studio 6’s interface for setting the ISP frequency.
Fuses (proceed with caution!)
Selecting Fuses in the Device Programming dialog 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, Atmel 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!
Lock Bits
Selecting Lock bits in the Device Programming dialog automatically causes the programmer to read the lock bits of
the target AVR. If the programmer is not connected to the target AVR when you select this tab, Atmel Studio displays
an error message. Lock bits allow you to secure your AVR by preventing further flash writing or reading. The lock
bits can be reset to a fully unlocked state by performing a chip erase (i.e. by clicking the Erase Device button in
the Memories section). Lock bits are usually only important if you wish to release a product to other people without
giving them access to the program it is running, or if you wish to make it more difficult to accidentally overwrite a
programmed chip.
3.b.3. Faster programming with F5 in Atmel Studio 6
The Device Programming dialog in Atmel Studio 6 is modal, which means you must close it after you are done
programming in order to go back to editing your source code. It takes 4 clicks to open up the dialog and initiate
