<h2>Disassembly view</h2>
<p>When debugging your application, the <img src="../../images/command_link.png" border="0" alt="" /> <a href='javascript:executeCommand("org.eclipse.ui.views.showView(org.eclipse.ui.views.showView.viewId=org.eclipse.cdt.dsf.debug.ui.disassembly.view)")' class="command-link"><b>Disassembly</b></a> view shows the loaded program as assembler instructions. When using the Disassembly view, you can do the following:</p>
<ul>
<li>Step through the disassembly instructions of your program using the <b>Instruction Stepping Mode</b> (<img src="../../reference/images/icon_instr_stepping_mode.png" width="18" height="16" align="absmiddle">) icon in the <a href="../debug/viewing_debug.htm">Debug</a> view (Figure 1). </li>
<li>Reposition the PC using the various move commands (Figure 1) by first selecting the line to move to, then select the command from the context menu.</li>
<li>Set breakpoints at the start of any assembler instruction by right-clicking the left hand column to view the context menu options </li>
</ul>
<p>Figure 1 shows the <b>Dissassembly</b> view stopped at a breakpoint.</p>
