Note the following details of the code protection feature on PICmicro®MCUs.
•The PICmicro family meets the specifications contained in the Microchip Data Sheet.
•Microchip believes that its family of PICmicro microcontrollers is one of the most secure products of its kind on the market today,
when used in the intended manner and under normal conditions.
•There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowl-
edge, require using the PICmicro microcontroller in a manner outside the operating specifications contained in the data sheet.
The person doing so may be engaged in theft of intellectual property.
•Microchip is willing to work with the customer who is concerned about the integrity of their code.
•Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable”.
•Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of
our product.

Quick Start
Introduction
This chapter is designed to get you up and running using the MPLAB ICE
emulator as quickly as possible. It is assumed that you have a working
knowledge of computer hardware terms, of the Windows®operating system,
of MPLAB IDE software and of general emulator operation.
Highlights
This chapter discusses:
•MPLAB ICE System Components
•Installing MPLAB ICE
•Setting Up MPLAB ICE
•Using MPLAB ICE
MPLAB ICE System Components
The MPLAB ICE system consists of these items (Figure 1):
1. Emulator pod
2. Parallel cable to connect the emulator pod to a PC
3. Power supply cable
4. Processor module with cable
5. Device adapter to connect the processor module to the transition socket
6. Transition socket to connect device adapter to target system
7. Logic probe connector

Installing MPLAB ICE
Hardware Installation
Follow the steps in this section to install the emulator hardware.
•Locate an unused LPT port
•Connect the MPLAB ICE pod to the parallel port using the parallel
cable.
Connect one end of the parallel cable to the parallel connector on the
MPLAB ICE pod and connect the other end to the LPT port on the PC
chassis. Secure both ends with the cable screws.

WARNING
Neither the PC nor MPLAB ICE should have power
turned on at this time.
WARNING Using MPLAB ICE in conjunction with a security
key, external disk drive, or other parallel device
(i.e., printer, Zip®drive, scanner) may result in
permanent damage to that device.
