<h4 class="section">Syntax</h4>



   <p>In the M68HC11 syntax, the instruction name comes first and it may

be followed by one or several operands (up to three). Operands are

separated by comma (<code>,</code>). In the normal mode,

<code>as</code> will complain if too many operands are specified for

a given instruction. In the MRI mode (turned on with <code>-M</code> option),

it will treat them as comments. Example:



<pre class="smallexample">     inx

     lda  #23

     bset 2,x #4

     brclr *bot #8 foo

     </pre>



   <p>The following addressing modes are understood:

     <dl>

<dt><dfn>Immediate</dfn>

     <dd><code>#</code><var>number</var><code></code>



     <br><dt><dfn>Address Register</dfn>

     <dd><code></code><var>number</var><code>,X</code>, <code></code><var>number</var><code>,Y</code>



     <p>The <var>number</var> may be omitted in which case 0 is assumed.



     <br><dt><dfn>Direct Addressing mode</dfn>

     <dd><code>*</code><var>symbol</var><code></code>, or <code>*</code><var>digits</var><code></code>



     <br><dt><dfn>Absolute</dfn>

     <dd><code></code><var>symbol</var><code></code>, or <code></code><var>digits</var><code></code>
