Important Environmental Considerations
Caution is necessary to minimize ESD (Electro-static Discharge) which can
damage electronic components. Use in a controlled environment where ESD
materials and practices are employed is highly recommended.
Limitations
EMU JTAG signals for boot modes/input triggers are not supported
The energy trace feature of the XDS110 debug probe is not supported
Bi-directional JTAG signals are not supported (i.e. cJTAG, SWD)

LED Operation
The Emulator Power LED (D1) will illuminate when the XDS110 supplies power
to the
ISO110
board. This may not occur until the debug session is launched or
a target connect has been initiated by Code Composer Studio.
The Target Power LED (D2) will illuminate only when the target board is supply-
ing power (J3 - Pin 5)
AND
the XDS110 is supplying power (D1 is illuminated).
