Abstract

PURPOSE:To obtain an efficient correspondence even between centralized processing devices of different types, by the mutual corresponding from a centralized processing device having a microcomputer to other centralized processing devices through the use of conventional input/output ports. CONSTITUTION:A centralized processing device 1 having a microcomputer reads input information from a key matrix circuit 6 supplied with a power supply voltage 8 via a key switch 62, a diode 63 and a matrix resistor 61, controls an output circuit 12 via an amplifying circuit 11 and a centralized processing device 2 reads input information from a key matrix circuit 7. The devices 1 and 2 make connection for mutual correspondence with a signal line 3, from output ports S9-S12 of the device 1 to input ports A4-A7 of the device 2 respectively, a signal line 4 from an output port S8 of the device 1 to the input port A8 of the device 2, and a signal line 5 from an output port B8 of the device 2 to an input port R4 of the device 1.
