ToolStick Debug Adapter TOOLSTICK DEBUG ADAPTER USERS GUIDE 1. Handling Recommendations To enable development, the ToolStick Base Adapter and daughter cards are distributed without any protective plastics. To prevent damage to the devices and/or the host PC, please take into consideration the following recommendations when using the ToolStick: Never connect or disconnect a daughter card to or from the ToolStick Base Adapter while the Base Adapter is connected to a PC. Always connect and disconnect the ToolStick from the PC by holding the large plastic connector. Figure 1. Proper Insertion Avoid directly touching any of the other components. Figure 2. Improper Insertion Manipulate mechanical devices on the daughter cards, such as potentiometers, with care to prevent the base adapter or daughter card from accidentally dislodging from their socket.

ToolStick Debug Adapter Specifications The ToolStick Debug Adapter, in conjunction with a ToolStick Base Adapter, provides the interface between the PCs USB port and the target devices in-system debug/programming circuitry. The 10-pin debug ribbon cable con- nects the adapter to the target board and the target devices debug interface. The ToolStick Debug Adapter sup- ports both Silicon Laboratories JTAG and C2 debug interfaces. Power is provided to the adapter from the USB connection to the PC. The ToolStick Debug Adapter is capable of providing power to a circuit board via pin 10 of the DEBUG connector. See the respective kit users guide for instructions on powering a target board from this source. Please note that not all of the Silicon Laboratories MCU development boards support being powered from the debug adapter. Table 1 shows the pin definitions for the debug ribbon cable connector. Notes: The ToolStick Debug Adapter requires a target system clock of 32 kHz or greater. With the default settings, the ToolStick Debug Adapter can supply up to 75 mA to a target system. Table 1.
