        <p>1. The fields in the above table are in the order of LSO to MSO. Where LSO = Least Significant Octet and MSO = Most Significant Octet</p>
        <p>2. The CGM Type and CGM Sample Location Fields are each a nibble (4bit), where the least significant nibble contains the Type and the most significant nibble contains the Sample Location. These two nibbles are packed as one single octet, the Least Significant Nibble means the four bits numbered 0, 1, 2 and 3 of the octet and the Most Significant Nibble means the four bits numbered 4, 5, 6 and 7 of that octet</p>
