Using the XDS110-ET Emulator With a Different Target
The XDS110-ET emulator on the LaunchPad can interface to most Arm Cortex-M devices, not just the
onboard MSP432P4111 device. This functionality is enabled by the J102
connector
and a 10-pin cable, such as the
(sold separately from the LaunchPad
development kit).
Header J102 follows the Cortex-M Arm standard; however, pin 1 is not a voltage sense pin. The XDS110-
ET outputs only 3.3-V JTAG signals. If another voltage level is needed, the user must provide level
shifters to translate the JTAG signal voltages. Additionally, 3.3 V of output power can be sourced from the
XDS110-ET when jumper JP102 is connected. This allows the XDS110-ET to power the external target at
3.3 V through pin 1. By default, JP102 is not populated as it does not explicitly follow the standard.
1. Remove jumpers on the JTAG signals on the isolation block, including RST, TMS, TCK, TDO, and TDI.
2. Plug the 10-pin cable into J102, and connect to an external target.
a. J102 allows the Arm Cortex Debug Connector standard outlined in
.
3. Plug USB power into the LaunchPad development kit, or power it externally.
a. JTAG levels are 3.3 V only.
b. 3.3-V power can be sourced through J102 by shorting the JP102 jumper.

EnergyTrace Technology
EnergyTrace technology is an energy-based code analysis tool that measures and displays the energy
profile of the application and helps to optimize it for ultra-low power consumption.
MSP432 devices with built-in Ener[CPU State] (or in short Ener) technology allow real-
time monitoring of internal device states while user program code executes.
Ener technology is supported on the LaunchPad development kit MSP432P4111 device and
XDS110-ET debug probe. EnergyTrace technology is available as part of Code Composer Studio IDE.
During application debug, additional windows are available for EnergyTrace technology.
To enable EnergyTrace technology:
1. Click Window > Preferences > Code Composer Studio > Advanced Tools > EnergyTrace™
Technology.
2. Check the Enable Auto-Launch on target connect box.
