Important information

• There is a limited amount of hardware breakpoints available on Atmel-ICE. 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
