47<P>This function decompresses data that was packed as 0 fixed bits. Please match the destination address <em><strong><code>dest</code></strong></em> to the 4-byte boundary.</P>
48<P><B><I>paramp</I></B> is the <CODE>MIUnpackBitsParam</CODE> structure data address for MI. The <CODE>MIUnpackBitsParam</CODE> structure comprises the following:<BR> �Source data byte count (u16) <BR> �Bit count for the &quot;1&quot; source data (u16:8)  <BR> �Bit count for the &quot;1&quot; destination data (u16:8)  <BR> �The offset to be added to the source data (u32:31)  <BR> �Flag to indicate whether to add an offset to the &quot;0&quot; data. (u32:1)</P>
