QUICK START GUIDE
MPLAB®ICD 4 In-Circuit Debugger
GETTING STARTED
Install the Latest Software
Download the MPLAB X IDE software from www.microchip.com/mplabx and install onto your computer. The installer
automatically loads the USB drivers. Launch MPLAB X IDE.
Connect to Target Device
1. Connect the MPLAB ICD 4 to the computer
using the USB cable.
2. Connect external power either to the target
board or debugger.

Create, Build and Run Project
1. Refer to the MPLAB X IDE User's Guide or online help
for instructions to install language tools, create or
open a project, and congure project properties.
2. Check that the conguration bits in your code match
the Recommended Settings below.
3. To execute your code in Debug mode, perform a
debug run (Debug>Debug Project). To execute
your code in Non-Debug (release) mode, perform
a run (Run>Run Project). To hold a device in Reset
after programming, use the Hold in Reset icon
in the toolbar.

ADDITIONAL INFORMATION
Target Circuit Design Precautions
• Do not use greater than 100 µF capacitance on Vdd: Depending on the overall load, it will
prevent the target from powering quickly when MPLAB ICD 4 is the source of power.
• Do not use capacitors on MCLR: They will prevent fast transitions of Vpp.
• Do not use multiplexing on PGC/PGD: They are dedicated for communications to
MPLAB ICD 4.
• Do not use capacitors on PGC/PGD: They will prevent fast transitions on data and
clock lines during programming and debug communications.
• Do not use diodes on PGC/PGD: They will prevent bidirectional communication
between MPLAB ICD 4 and the target PIC®MCU.
• Do not exceed recommended cable lengths: Refer to the Hardware Specication of
the MPLAB ICD 4 online help or user's guide for cable lengths.

Target Application
Device
* MPLAB ICD 4 is controlled by a 32-bit MCU with an Arm®Cortex®-M7 core.
** Target device must be running with an oscillator for the debugger to function
as a debugger.
*** If the device has AVdd and AVss lines, they must be connected for the
debugger to operate.
