Important information

• USB driver installation instructions for Atmel AVR JTAGICE3
  The USB driver for Atmel AVR JTAGICE3 is NOT automatically installed during the product installation.
  You must manually run the driver-atmel-installer-x86-7.0.1417.msi installer or the driver-atmel-installer-x64-7.0.1417.msi installer to install the driver.

• There is a limited amount of hardware breakpoints available on AVR JTAGICE3. If you are using the CLIB library, the debugger will set internal breakpoints on the exit label, and if terminal I/O is used, a breakpoint will also be set on the putchar/getchar label. One breakpoint will also be set if the C-SPY option Run to has been selected.

  If you are using the DLIB library, the debugger will set a system breakpoint on the __DebugBreak label.

  To use more breakpoints for other purposes during debugging you can deselect the C-SPY option Run to and the linker option With I/O emulation modules.

• Supported AVR devices
  The following AVR devices are supported by the IAR C-SPY driver for AVR JTAGICE3:
