* The amount of data that can be transmitted at one time depends on the type of data, and
data can be received only from the specified starting address and size. Refer to the
Address and Size given in Section 3 (p. 146).
* Data larger than 128 bytes must be divided into packets of 128 bytes or less. If "Data Set
1" is transmitted successively, there must be an interval of at least 40 ms between
packets.
