<p>The macro syntax used on the MSP 430 is like that described in the MSP
430 Family Assembler Specification.  Normal <code>as</code>
macros should still work.
</p>
<p>Additional built-in macros are:
</p>
<dl compact="compact">
<dt><code>llo(exp)</code></dt>
<dd><p>Extracts least significant word from 32-bit expression &rsquo;exp&rsquo;.
</p>
</dd>
<dt><code>lhi(exp)</code></dt>
<dd><p>Extracts most significant word from 32-bit expression &rsquo;exp&rsquo;.
</p>
</dd>
<dt><code>hlo(exp)</code></dt>
<dd><p>Extracts 3rd word from 64-bit expression &rsquo;exp&rsquo;.
</p>
</dd>
<dt><code>hhi(exp)</code></dt>
<dd><p>Extracts 4rd word from 64-bit expression &rsquo;exp&rsquo;.
</p>
</dd>
</dl>

<p>They normally being used as an immediate source operand.
