ICE 4000 User’s Guide
MPLAB ICE 4000 communicates with the PC via a USB port.
1. Select Debugger>Settings and click on the Port tab.
2. Select a communications port, where ICEUSB-x are the available USB ports.
Click Apply to accept the setting in this tab of the Settings dialog.
MPLAB ICE 4000 allows the emulator processor chip to be powered by the emulator
pod (5V) or the target system (2.5V to 5V). The emulator defaults to Processor Power
from Emulator (system power) when first initialized.
For information on processor module power issues, please refer to the MPLAB ICE
4000 Processor Module and Device Adapter Specification.

Refer to the MPLAB ICE 4000 Processor Module and Device Adapter Specification for
processor module power requirements before configuring the system for target system
power.
