4.3.1.1 Device Device is chosen by selecting the correct device from the Pull-down menu. This group
also includes a button that performs a chip-erase on the selected device, erasing both
the FLASH and EEPROM memories.
4.3.1.2 Programming Mode This group selects programming mode. AVRISP only supports the ISP low-voltage
mode. Checking the “Erase Device Before Programming” will force AVRISP to perform
a chip-erase before programming the device. Checking the “Verify Device After Pro-
gramming” will force AVRISP to perform a verification of the memories after
programming.
4.3.1.3 Flash If the AVRISP User Interface is opened without a project loaded in AVR Studio, the “Use
Current Simulator/Emulator Flash Memory” option will be grayed out. When a project is
open this option allows programming of the Flash memory content currently present in
the Flash Memory view of AVR Studio. For more information about AVR Studio memory
views, please take a look in the AVR Studio help system.
If no project is running, or the source code is stored in a separate HEX file, select the
“Input HEX File” option. Browse to the correct file by pressing the
button, or write the
complete path and filename in the text field. The selected file must be in “Intel-hex” for-
mat or “extended Intel-hex” format.
4.3.1.4 EEPROM If the AVRISP User Interface is opened without a project loaded in AVR Studio, the “Use
Current Simulator/Emulator EEPROM Memory” option will be grayed out. When a
project is open this option allows programming of the EEPROM memory content cur-
rently present in the EEPROM Memory view. For more information about AVR Studio
memory views, please take a look in the AVR Studio help system.
If no project is running, or the source code is stored in a separate HEX file, select the
“Input HEX File” option. Browse to the correct file by pressing the
button, or write the
complete path and filename in the text field. The selected file must be in “Intel-hex” for-
mat or “extended Intel-hex” format.
4.3.2 "Fuses" Settings On the “Fuses Settings” tab, an overview of accessible fuses are presented. Some
fuses are only available during Parallel /High-voltage programming. These will be dis-
played, but are not accessible when operating in ISP programming mode. Press the
“Read” button to read the current value of the fuses, and the “Write” button to write the
