<P>PROBLEM TO BE SOLVED: To appropriately switch an operation mode to a wake-up mode without depending on influences such as a noise in a communication system which performs communication on the basis of a clock pulse transmitted from a master node. <P>SOLUTION: When a master node determines presence/absence of a wake-up factor and determines that the wake-up factor is present, a mode signal is set as "1" to output a clock pulse to a bus communication path. On the other hand, a slave node determines whether or not the clock pulse from the master node is outputted to the bus communication path (S260). When the slave node determines that the clock pulse is outputted (S260:YES), the mode signal is set as "1" (S270) to switch the operation mode to the wake-up mode. Thus, wake-up of the slave node is performed with the clock pulse from the master node. <P>COPYRIGHT: (C)2013,JPO&INPIT |
