2. About the Daughter Boards
The C8051T63x Development Kit includes an Emulation Daughter Board (EDB) and a QFN Socket Daughter
Board (QFN-DB). The EDB has an installed C8051F336 device, which is a Flash-based device that can be used
for the majority of C8051T63x code development. The QFN-DB is intended to allow both programming and
system-level debugging of C8051T63x devices directly.
A C8051T63x device cannot be erased once it has been program med; so, it is advisab le to use the C80 51F 336 for
the majority of code development. Refer to “AN339: Differences between the C8051F336 and the C8051T63x
device family” for more details on how the C8051F336 can be used to develop code for the C8051T63x device
family.

C8051T63x-DK
The Configuration Wizard utility helps accelerate development by automatically generating initialization source
code to configure and enable the on-chip reso urces ne eded by most design project s. In just a few steps, th e wizard
creates complete startup code for a specific Silicon Laboratories MCU. The program is configurable to provide the
output in C or assembly language.
For more information, refer to the Configuration Wizard documentation. Documentation and software is available
on the kit CD and from the downloads webpage: www.silabs.com/mcudownloads.
4.6. Keil uVision2 and uVision3 Silicon Laboratories Drivers
As an alternative to the Silicon Laboratories IDE, the µVision debug driver allows the Keil µVision2 and µVision3
IDEs to communicate with Silicon Laboratories’ on-chip debug logic. In-system Flash memory programming
integrated into the driver allows for rapid updating of target code. The µVision2 and µVision3 IDEs can be used to
start and stop program execution, set breakpoints, check variables, inspect and modify memory contents, and
single-step through programs runn ing on the ac tu al target ha rd wa re .
For more information, refer to the µVision driver documentation. The documentation and software are available on
the kit CD and from the downloads webpage: www.silabs.com/mcudownloads.
4.7. ToolStick Terminal
The onboard debug circuitry provides both an in-system programming and debugging interface and a
communications interface to the target microcontroller's UART. The ToolStick Terminal s oftware can access the
debug hardware's communications path and provides a terminal-like interface on the PC. Note that for concurrent
debugging and UART communications, the CP2103 USB-to-UART bridge is also included onboard.
In addition to the standard terminal functions (Send File, Receive File, Change Baud Rate), two GPIO pins on the
target microcontroller can be controlled using the terminal for either RTS/CTS handshaking or softwareconfigurable purposes. The ToolStick Terminal software is available on the downloads webpage: www.silabs.com/
mcudownloads.

5. Using the Keil Software 8051 Tools with the Silicon Laboratories IDE
To perform source-level debugging with the IDE, configure the Keil 8051 tools to generate an absolute object file in
the OMF-51 format with object extensions and debug records enabled. Build the OMF-51 absolute object file by
calling the Keil 8051 tools at the command line (e.g., batch file or make file) or by using the project manager built
into the IDE. The default configuration when using the Silicon Laboratories IDE project manager enables object
extension and debug record generation. Refer to "AN104: Integrating Keil 8051 Tools into the Silicon Labs IDE" in
the SiLabs\MCU\Documentation\Appnotes directory on the CDROM for additional information on using the Keil
8051 tools with the Silicon Laboratories IDE.
To build an absolute object file using the Silicon Laboratories IDE project manager, you must first create a project.
A project consists of a set of files, IDE configuration, debug views, and a target build configuration (list of files and
tool configurations used as input to the assembler, compiler, and linker when building an output object file). The
following sections illustrate the steps necessary to manually create a project with one or more source files, build a
program, and download it to the target in preparation for debugging. (The IDE will automatically create a single-file
project using the currently open and active source file if you select Build/Make Project before a project is defined.)
5.1. Creating a New Project
1. Select “ProjectNew Project” to open a new project and reset all configuration settings to default.
2. Select “FileNew File” to open an editor window. Cr eate your source file(s) and save the file(s) with a
recognized extension, such as .c, .h, or .asm, to enable color syntax highlighting.
3. Right-click on "New Project" in the Project Window. Select “Add Files to Project”. Select files in the file browser,
and click “Open”. Continue adding files until all project files have been added.
4. For each of the files in the Project Window that you want assembled, compiled, and linked into the target build,
right-click on the file name, and select “Add File to Build”. Each file will be assembled or compiled as
appropriate (based on file extension) and linked into the build of the absolute object file.
Note: If a project contains a large number of files, the "Group" feature of the IDE can be used to organize them. Righ t-click on
"New Project" in the Project Window. Select “Add Groups to Project”. Add predefined groups or add customized groups.
Right-click on the group name, and choose “Add File to Group”. Select files to be ad ded. Continue adding files until all
project files have been added.
5.1.1. Building and Downloading the Program for Debugging
1. Once all source files have been added to the target build, build the project by clicking on the “Build/Make
Project” button in the toolbar or by selecting “ProjectBuild/Make Project” from the menu.
Note: After the project has been built the first time, the Build/Make Project command will only build the files that have been
changed since the previous build. To rebuild all files and project dependencies, click on the “R ebuild All” button in the
toolbar or select “Project
2. Before connecting to the target device, several connection options may need to be set. Open the Connection
Options window by selecting “OptionsConnection Options...” in the IDE menu. First, select the "USB Debug
Adapter" option. The USB Debug circuitry is integrated onto the C8051T630 Motherboard.
3. Next, the correct debug interface must be selected. C8051T63x family devices and the F336 all use the Silicon
Labs "C2" 2-wire debug interface. Once all the selections are made, click the OK button to close the window.
4. Click the “Connect” button in the toolbar, or select “DebugConnect” from the menu to connect to the de vice.
5. Download the project to the target by clicking the “Download Code” button in the toolbar.
Note: To enab le automatic downloading if the program build is successful, select “Enable Automatic Connect/Download after
Build” in the “ProjectT arget Build Configuration” dialog. If errors occur during the build process, the IDE will not attempt
the download.
6. Save the project when finished with the debug session to preserve the current target build configuration, editor
settings, and the location of all open debug views. To save the project, select “ProjectSave Project As...” from
the menu. Create a new name for the project, and click on “Save”.
Rebuild All” from the menu.
