摘要： A communication system in which an operating voltage can be selected from a plurality of interface voltages enables an interface voltage to be switched in a stable manner during operation of the system. When the interface voltage is to be switched, a host device (1) and a slave device (2) perform the switching while maintaining the signal level of buses in a stable manner. This structure enables the communication system to switch an interface voltage using a small number of signal lines.
