APPLICATION NOTE

Guidelines for connecting via JTAG protocol to the STR71x

microcontroller

INTRODUCTION

This application note provides guidelines on how to connect a Host debugger to a target

STR71x board via a JTAG protocol converter, taking into account the internal features of the

STR71x microcontroller product family.

This document is targeted for third party tool suppliers or application engineers interested in

connecting to the STR71x using the JTAG connector. For basic references on the JTAG tar-

geted for the ARM core, please refer to the ARM7TDMI Technical Reference manual
