<p>Management commands for optional Test Inputs. </p>
|
|
<p>CMSIS-DAP provides a command set that allows to implement an optional Test Input (TI) management in the <b>Debug Unit</b>. Recording of up to 16 different Test Inputs is possible. Test Input values can be recorded as BYTE, SHORT, or WORD. The <b>Debug Unit</b> may include scaling parameters and dynamic ranges for a channel (for example a 14-bit value with a 2-bit range selection).</p>
|
|
<p>Test Inputs could be used for various scenarios, for example:</p>
|
|
<ul>
|
|
<li>capture power measurement from A/D converters.</li>
|
|
<li>capture wait states or cache misses from a memory system.</li>
|
|
<li>capture data transfer parameters of an RF interface.</li>
|
|
<li>test input pins of a Debug Unit.</li>
|
|
</ul>
|
|
<p>These Test Inputs can be recorded continuously with a specified trace recording frequency. The recording allows you to correlate the Test Input information with program execution. For recording of the CMSIS-DAP Firmware includes an optional Trace Data Management based on configurable memory blocks. This Trace Data Management also captures SWO trace information.</p>
