The program will automatically decode your files whether they are in Intel Hex format, Atmel Generic, Binary or Motorola S record. The file you choose will be loaded into the window, then it is displayed on the top of the desktop. Therefore, if you have the EEPROM Data Memory window on top, it will load the data into that window. - Page 14 How to Use the Software megaAVR™ Starter Kit Manual...
