649 Note:
650 The high 2 bits of the first byte reveal how many
651 follow bytes are in the PkgLength. If the
652 PkgLength has only one byte, bit 0 through 5 are
653 used to encode the package length (in other
654 words, values 0-63). If the package length value
655 is more than 63, more than one byte must be
656 used for the encoding in which case bit 4 and 5 of
657 the PkgLeadByte are reserved and must be zero.
658 If the multiple bytes encoding is used, bits 0-3 of
659 the PkgLeadByte become the least significant 4
660 bits of the resulting package length value. The next
661 ByteData will become the next least
662 significant 8 bits of the resulting value and so on,
663 up to 3 ByteData bytes. Thus, the maximum
