<h1><a class="anchor" id="Names"></a>
Names</h1>
<p>All <b>name</b> tags must comp ly with the ANSI C identifier naming restrictions. In particular, they must not contain any spaces or special characters. This is necessary to support the generation of device header files thus providing consistency between the names being shown by the debugger and the symbols being used in the CMSIS compliant target software.</p>
<h1><a class="anchor" id="Constants"></a>
Constants</h1>
<p>Number constants shall be entered in hexadecimal, decimal, or binary format. </p>
<ul>
<li>The Hexadecimal format is indicated by a leading <b><span class="XML-Token">0x</span></b>. </li>
<li>The Binary format is indicated by a leading <b><span class="XML-Token">#</span></b>. </li>
<li>All other formats are interpreted as decimal numbers. </li>
<li>The element <em>&lt;enumeratedValue&gt;</em>.<em>&lt;value&gt;</em> can be used to define constants.</li>
</ul>
<h1><a class="anchor" id="Comments"></a>
Comments</h1>
<p>Comments have the standard XML format. </p>
<ul>
<li>Start a comment with <b><span class="XML-Token">&lt;!--</span></b>. </li>
<li>End a comment with <b><span class="XML-Token">--&gt;</span></b>.</li>
</ul>
<h1><a class="anchor" id="_"></a>
Empty Tags</h1>
<ul>
<li>Single tags are not supported (for example, <em>&lt;name\&gt;</em>).</li>
<li>The tag content must not consist of an empty string. Omit optional tags instead.</li>
