Extended messages (Figure 4–1).
Two-byte messages consist of two consecutive bytes. The value of the first byte, as
defined in Table 4–1, determines which message is to be transmitted. The second byte is
a parameter byte that is used as defined in the message description.
A value of 1 in the first byte indicates the beginning of a multiple-byte extended
message. The minimum number of bytes sent for an extended message is three. The
extended message format is shown in Figure 4–1 and the data fields are described in
Table 4–3.
