CONSTITUTION:A microcomputer muCP16 for tuner is connected to a tuner 14 of an audio equipment and a muCP20 for deck is connected to a tape deck 18. The two muCP16, 20 are connected by a signal line l1 for clock, a signal line l2 for data sending request and a signal line l3 for data sending. An display unit 10 that can be used in common is connected to the muCP16 to control display of the display unit 10. Display data are sent from the muCP20 to the muCP16 that outputs clock and data sending request following sending request and tuner data and deck data are switched and displayed in the display unit 10. By this constitution, the equipment is made simple and small and function is multiplied without providing a data selector etc. |
