<p>CRC - Cyclic Redundancy Check (16-bit)</p>
<p>A CRC-checksum is used to be sure, the data hasn't changed or is false. To create a CRC-checksum, initialise a check-variable (unsigned short), and set this to zero. Than call for every byte in the file (e.g.) the procedure updateCRC16 with this check-variable as the first parameter, and the byte as the second. At the end, the check-variable contains the CRC-checksum.</p>
