3. Hardware Setup
Refer to Figure 1 for a diagram of the hardware configuration.
1. Connect the USB Debug Adapter to the DEBUG A connector on the target board with the 10-pin ribbon cable.
2. Connect one end of the USB cable to the USB connector on the USB Debug Adapter.
3. Verify that shorting blocks are installed on the target board as shown in Figure 4 on page 9.
4. Connect the other end of the USB cable to a USB Port on the PC.
5. Connect the ac/dc power adapter to power jack P1 on the target board.
Notes:
• Use the Reset icon in the IDE to reset the target when connected during a debug session.
• Remove power from the target board and the USB Debug Adapter before connecting or disconnecting the
ribbon cable from the target board. Connecting or disconnecting the cable when the devices have power can
damage the device and/or the USB Debug Adapter.

  • Page 15 C8051F540DK 7.14. Target Board Pin Assignment Summary Some GPIO pins of the C8051F540 MCU can have an alternate fixed function. For example, pin 30 on the C8051F540 MCU is designated P0.4, and can be used as a GPIO pin. Also, if the UART0 peripheral on the MCU is enabled using the crossbar registers, the TX signal is routed to this pin.
