Abstract

PURPOSE: To reduce the number of signal lines extending to an external device by making alternations between a digital signal and analog signal.
CONSTITUTION: This circuit is provided with input-output switching circuit 8 which outputs analog signals from signal line 3 to signal line 5 and intermittent digital signals arriving from external device 27 via signal line 5 to signal line 6, decoder 9 for digital signals outputted intermittently onto signal line 6, and memory 10 stored with decoded outputs. Then, one of a plural analog inputs 2 is selected 1 according to information stored in memory 10 and outputted to signal line 3.
