3.1 Power and Self Test

An external 9V power supply (AC002014) is required to power the MPLAB® ICE 4 In-Circuit Emulator and optionally the target. This power supply comes with the emulator kit. Connect the 3-pronged plug into a power socket and the tip end into the top of the emulator as shown in the figure below.

Note: USB cannot power the MPLAB ICE 4 unit.

Power-up Self Test

The MPLAB ICE 4 unit preforms a built-in self-test (or BIST) during power-up. Errors that occur during this test are reported in the MPLAB X IDE Output window. Depending on the error, LED colors may indicate the error as well.

Power the Target

It is possible to power the target using the emulator. For details, see Power Specifications.

Select this option in the Project Properties window (see figure below). Also select the desired target voltage.
