Installation Requirements
 XDS110 Debug probe
 20-pin JTAG Ribbon Cable (from XDS110 Debug Probe)
 Target Board with 1149.1 JTAG interface and I/O voltages from 1.8 to 5.0 volts
 Pin Converter to target board JTAG connection (optional)
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).

2Cable Connections
1. If attached, detach the 14-pin and 20-pin ribbon cables from the XDS110 de-
bug probe’s AUX and DEBUG connectors.
2. Attach the supplied two inch 20-pin and 14-pin ribbon cables (if not already
attached) to J1 and J2 of the ISO110 board respectively (see figure 1).
3. Attach the other end of the 20-pin and 14-pin ribbon cables to the correspond-
ing XDS110 AUX and DEBUG connectors (see figure 1).
4. Attach the XDS110’s 20-pin JTAG ribbon cable to J3 of the ISO110.
5. Attach the other end of the XDS110’s 20-pin JTAG cable to your target board.
6. The stand-offs are optional and attach to the holes shown in figure 4 to prevent
the PCB from touching the bench or table underneath as needed.

Target board
To use the ISO110 with Code Composer Studio, you need to configure the
XDS110 Debug Probe setting to output 3.3v on the AUX connector. The
steps below describe how to accomplish this using the CCS target configura-
tion dialog. This assumes that you already followed the steps in section 2.
Please refer to figure 2 below when following these steps.
A. Start Code Composer Studio.
B. Edit your current XDS110 target configuration or create a new one (File >
New > Target Configuration File)for XDS110 and your target device.
The example in figure 2 uses the XDS110 and an F28379D device.
C. Select the Advanced tab in the target configuration.
D. Select the XDS110 Debug Probe in the All Connections tree view.
E. Select Probe supplied power option in the Power Selection of the
Connection Properties.
F. This will display a voltage field text box where you will enter 3.3.
G. Save the setup by pressing the Save button.
Now you are ready to launch the debug session.
