<p>PURPOSE:To miniaturize an aggregated wiring system by using a CCU to process many inputs being in AND condition existing in an automobile and inputs being in OR relation by means of software. CONSTITUTION:A control section consists of a synchronizing circuit 61 synchronizing reception data of a line 68 with a clock, a control circuit 62 using the said clock to apply control of shift of a shift register, control of interruption and transmission error control of data, and an address comparator 63 comparing the address given from a line 67 with an address representing destination included in the reception data. The interface section consists of a shift register 64 applying serial/parallel conversion, an A/D converter control circuit 65 controlling an A/D converter 3 for serial input/output and an input/output buffer whose input/output is changed by the address input of a line 67 and connected to the input/output interface 4. Thus, the relation between the output and input is controlled in terms of the software at each time.</p> |
