6.7. Single-Stepping through Firmware
The IDE supports the ability to single-step through firmware one assembly instruction at a time. The IDE reads the
Flash from the device, converts the instructions to assembly and displays them in a disassembly window. The
following steps show how to open the disassembly window and single step through firmware.
1. If there is already not a breakpoint set on line of code that increments the Num_LED_Flashes variable, set the
2. Start the processor using the “Go” button and wait till it stops on the breakpoint.
3. Select View  Debug Windows  Disassembly. The disassembly window will appear on the right-hand side
4. To execute one assembly instruction at a time, click the “Step” button on the toolbar or select the Debug 
The disassembly window has three columns. The left column is the address of the instruction in Flash. The middle
column is the instruction in hex. The right column is the disassembled instruction. The Disassembly debug window
and the capability to single-step through firmware allows a developer to see exactly what instructions are executed
and their output.
6.8. Using ToolStick Terminal
This section describes how to use ToolStick Terminal to communicate with UART from the PC to the daughter card
through the ToolStick Base Adapter.
1. If the Silicon Labs IDE is open, close the IDE. The IDE and the ToolStick Terminal cannot communicate with the
