<p>Configure the parameters for SWO mode. </p>
<h2>CMSIS-DAP SWO (Serial Wire Output)</h2>
<p>CMSIS-DAP (CoreSight Debug Access Port) specifies debug protocol and interface for devices with CoreSight Debug and Trace. Currently it only supports debug but not also trace.</p>
<p>The following extension adds support for trace over SWO (Serial Wire Output).</p>
<p>SWO add-on is a compatible extension of the existing CMSIS-DAP specification. Existing debugger implementations on PC do not require any modifications for debugging. They only need to be extended in order to support trace.</p>
<p>The following new commands are added:</p>
<ul>
<li><a class="el" href="group___d_a_p___s_w_o___transport.html">DAP_SWO_Transport</a></li>
<li><a class="el" href="group___d_a_p___s_w_o___mode.html">DAP_SWO_Mode</a></li>
<li><a class="el" href="group___d_a_p___s_w_o___baudrate.html">DAP_SWO_Baudrate</a></li>
<li><a class="el" href="group___d_a_p___s_w_o___control.html">DAP_SWO_Control</a></li>
<li><a class="el" href="group___d_a_p___s_w_o___status.html">DAP_SWO_Status</a></li>
<li><a class="el" href="group___d_a_p___s_w_o___data.html">DAP_SWO_Data</a></li>
</ul>
<p>Format of the new commands is specified below using CMSIS-DAP documentation style. Note: 16-bit values (SHORT) and 32-bit values (WORD) are encoded as little-endian.</p>
<p>The following existing commands are extended:</p>
<ul>
<li><a class="el" href="group___d_a_p___info.html">DAP_Info</a> </li>
</ul>
