<p>A device in which a main controller which controls the operations of electric apparatuses is connected with a subcontroller which performs clock operation via a communication means, is characterized in that the main controller generates data having a predetermined period according to a reference clock and sends out the data via the communication means, and the subcontroller receives the data and performs the clock operation according to the period of the data. Since clock information is created according to the communication period of the data, the subcontroller is not required to have a reference oscillator of high accuracy.</p> |
