Device Power (CHB) Setup

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.

  1. In the Project Properties window, click on the Real ICE category and select the Power option category.
  2. Locate the checkbox Power target circuit from REAL ICE. Check to power the target from the emulator. Uncheck to power the target with its own power supply.
  3. Click Apply or OK.

Power Monitor Usage

Regardless of which Power Data mode you are using, you need to change the type of power measurement:

  1. In the Project Properties window, click on the Real ICE category and select the Trace and Profiling option category.
  2. Under Power Measurement, select Processor Only (1μA - 9mA).
  3. Click OK.
