<p><P>PROBLEM TO BE SOLVED: To provide a "reset circuit" which enables a host unit to positively initialize a device unit, and can positively start or resume communication between the host unit and the device unit. <P>SOLUTION: The reset circuit is arranged in data signal lines 9, 10 of a bus 4 via which a device unit 3 is connected to a host unit 19. When the device unit 3 is connected to the host unit 19 via the bus 4, the reset circuit is constituted so as to perform reset for initializing the device unit 3, by reducing the voltage level of the data signal lines 9, 10 from a high level to a low level. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
