37<H2>Description</H2>
38<P>This calculates CRC-16. The data address <em><strong><code>datap</code></strong></em>   needs to be a 2-byte boundary. The size <em><strong><code>size</code></strong></em> needs to be a multiple of 2. CRC stands for Cyclic Redundancy Check (Cyclic Redundancy Test) and is an error detection method.</P>
