<p>PURPOSE: To realize a data control system used in a TV, etc., capable of shortening a data setting time increasing according to the number of slave devices. CONSTITUTION: This data control system is constituted to be provided with a remote control reception block 1, a master CPU 2, an EEPROM 3, plural slave devices containing the slave device (1) 5 and the slave device (2) 6, a power source (1) 4 supplying power to the remote control reception block 1, the master CPU 2, the EEPROM 3, the slave device (1) 5 and the slave device (2) 6 and the power source (2) 7 supplying the power to the slave device (1) 5 and the slave device (2) 6. Since the power is supplied from the power source (1) 4 to a register for holding the receiving data in the slave device even at a stand-by time, the held inside data are not erased, and the necessity that the data are transferred from the master CPU 2 again is eliminated even in the case where the system is returned to a stationary operation state by turning on the power source.</p> |
