F280049C LaunchPad自带XDS模块，不过我需要验证外购的XDS110 DEBUG PROBE，发现无法工作，CCS上提示（下面之一）
Trouble Halting Target CPU:
(Error -1156 @ 0x0)
Device may be operating in low-power mode. Do you want to bring it out of this mode? Choose 'Yes' to force the device to wake up and retry the operation. Choose 'No' to retry the operation without waking the device.
(Emulation package 9.2.0.00002)
Error connecting to the target:
(Error -2131 @ 0x0)
Unable to access device register. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK).
(Emulation package 9.2.0.00002)
我在target configuration里面也看了一下，发现有4线JTAG和2线JTAG之分，不过我试了所有情况都无法仿真，（而默认配置是2线，采用LaunchPad上面的XDS是可以仿真的），我怀疑会不会是外购的XDS110只支持4线JTAG，而LaunchPad只支持2线JTAG的原因。
