Abstract
A communication system includes a master control unit, a plurality of slave control units, and buses connecting the master control unit and the slave control units for the asynchronous communication. When the master control unit starts the communication, each slave control unit transmits a plurality of data bits represented by whether the buses be driven to the master control unit in data transmission periods assigned to the slave control units based on a start of communication, and the master control unit drives the buses to insert a period for supplying power while data bits are being transmitted in the data transmission period. The slave control unit provides a non-driving period, which stops driving the buses, at an end of the data bit transmission period.
