MSP-EXP430G2: 问一个目标板的问题?

Part Number: MSP-EXP430G2


不知道这个SBW的接口可不可以仿真另一个目标板。就是将跳线J3全部断开,使用J4的2.3.4.5四个脚,对应 VCC,SBWTCK ,SBWTDIO,GND.


  • 1、可以仿真其他板子,这可以看成就是一个JTAG接口。

    2、这个你可以看一下user's guide中的说明:On some Spy-Bi-Wire capable MSP430 devices, TEST/SBWTCK is very sensitive to rising signal edges that can cause the test logic to enter a state where an entry sequence (either 2‑wire or 4-wire) is not recognized correctly and JTAG access stays disabled. Unintentional edges on SBWTCK can occur when the JTAG connector is connected to the target device.
