* 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.
