1-4-3. NEW SERIAL DATA TRANSMISSION
1. Serial data transmission
To exchange the data among the microprocessors, the
serial data transmission is used.
Serial data transmission is used because of the relatively
large amount of information that can be sent in a signal data
line.
Actually two lines are required in this system, an in/out data
line and a clock line.
The data in/out line between each microprocessor is
timeshared.
