<p><P>PROBLEM TO BE SOLVED: To provide a bus system such as an I2C bus with low power consumption, which is suitable for compact high density electronic equipment such as a mobile phone. <P>SOLUTION: After a stop condition is detected by a stop condition detecting circuit 23, a Low level generated by a Low output circuit 24 is inputted through a switch 25 to an SCL 28, so that the arbitration function of a slave device 27 can be functioned to stop the operation of the slave device 27, and the power consumption of this system can be reduced. Also, after the stop condition is detected, a power source 29 to the slave device 27 is turned off, so that the operation of the slave device 27 can be stopped to further reduce the power consumption of the system. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
