Introduction

It is hard to imagine debugging an embedded application without resources built into the processor core. Today, we take that for granted. In the early days of embedded applications, that wasn’t the case. Every transistor was precious, as was every I/O pin on a package. The thought of adding extra transistors to support the development process and then shipping these processors to ...
