title: How do I capture and view ITM trace information on a Cortex-M4 MCU?
body: <p>I would like to capture, decode, and view ITM trace information for a Cortex-M4 MCU (in my case, an Atmel SAM4S).  In particular, I want to capture exceptions and user trace data relative to other signals on my board (i.e. show all signals and trace information on same timeline).</p>
