The Device Power configuration is used in cases where only the microcontroller or a section of the target application is desired to be monitored.
Hardware Setup
Connecting the Channel B (CHB) Voltage Out (VO) terminal to the device or target section allows small current measurements to be made, typically in the range from μA to a few mA. The modular cable still needs to be connected to provide communication to the emulator.
Connecting the Channel B (CHB) Voltage In (VI) terminal to the target power supply section allows voltage measurements to be made.

Software Setup – Power
In this configuration, you can continue powering the target from the emulator or you can power the target board independently.
- In theProject Properties window, click on theReal ICE category and select thePower option category.
- Locate the checkboxPower target circuit from REAL ICE. Check to power the target from the emulator. Uncheck to power the target with its own power supply.
- ClickApply orOK.
Power Monitor Usage
Regardless of which Power Data mode you are using, you need to change the type of power measurement:
- In theProject Properties window, click on theReal ICE category and select theTrace and Profiling option category.
- UnderPower Measurement, selectProcessor Only (1μA - 9mA).
- ClickOK.
