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.

C: 80 M: 45 Y: 0 K: 55 PMS: 7694C

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.
