Data transmission

TD-8 can transmit and receive the various parameters using System Exclusive messages.
The exclusive message of TD-8's data has a model ID of 00H 20H and a device ID of 10H
(17). Device ID can be changed in TD-8.
Request data 1 RQ1 (11H)
This message requests the other device to send data. The Address and Size determine the
type and amount of data to be sent.
When a Data Request message is received, if the device is ready to transmit data and if the
address and size are appropriate, the requested data will be transmitted as a "Data Set 1
(DT1)" message. If not, nothing will be transmitted.
