To program the attached target without interfering with the LaunchPad socket board jumper connections TEST and RST of J3 must be open The interface to the eZ430 target board is always connected to the MSP EXP430G2 emulator so the programming and debugging of a connected LaunchPad target device is possible only if the eZ430 target is not connected on the same time The application UART on the other hand is connected directly to the LaunchPad target device and jumper J3 can be closed to monitor the transmission from the LaunchPad target to the attached eZ430 This way both possible connections from the device to the PC and from the device to the eZ430 can be established without changing the direction of the UART pins Table 2 shows the pin out of the debugging interface J4 Table 2 eZ430 Debugging Interface Pin Signal Description 1 TXD UART transmit data output UART communication from PC MSP430G2xx to eZ430 target board 2 GND Power supply ground 3 RST SBWTDIO Reset Spy Bi Wire test data input output during programming and test 4 TEST SBWTCK Test mode for JTAG pins Spy Bi Wire test clock input during programming and test 5 VCC Power supply voltage 6 RXD UART receive data input UART communication from eZ430 target board to PC MSP430G2xx 45 Connecting a Crystal Oscillator The MSP EXP430G2 LaunchPad offers a footprint for a variety of crystal oscillators The XIN and XOUT signals of the LFX
