When selecting ”Device programming” from the Tools menu, Atmel Studio will display this programming dialogue. The user may notice that, compared to AVR Studio, the programming dialogue is brand new and contains a lot more useful information about the target MCU. At this stage, users can just run with the default settings and be done with it. Taking a look some of the features of the Device Programming dialogue: The first screen shows the interface options, which in this case are the JTAG settings. Note how the debugger has already connected with the device and verified that the JTAG ID stored in the chip matches the ID of our target device. The in-circuit debugger has also measured the main supply voltage and verified that 3.3 V is within the allowed operating voltage for the target device.
