Debugging in EM2 can be disabled through the configuration header. If using Simplicity Studio, this header can also be configured using the Project Configurator by selecting the "Device Init: EMU" configuration component.

Note
Voltage scaling for Energy Modes 0 to 3 are configured by the Power Manager .
