Header Specification

INTRODUCTION

in-circuit debugging capabilities for specific Microchip devices.

A special ICD/ICE device is connected to a header board to be used with MPLAB ICD 2.

This device is mounted on the top of a header and its signals are routed to the

MPLAB ICD 2 connector (Figure 1). On the bottom of the header is a socket that is

used to connect to the target board.

FIGURE 1:

Special ICD/ICE versions of selected devices are needed to provide one or more of the

following:

• the built-in debug circuitry that a device may lack

• additional pins for the clock, data and MCLR functions required for ICD

• dedicated program/data memory for ICD

ICD versions are labeled with an ICD suffix (Device-ICD). For some devices, ICE

versions are available (Device-ICE) and may be used with MPLAB ICD 2 as ICD

devices.
