PURPOSE:To attain the interface with an optional number of switches by using three signal lines to an operation part to an operation interface part and delivering the input data by means of a counter. CONSTITUTION:The 1st counter 10 is provided to an operation part OP, and the 2nd counter 11 is provided to an operation interface part IF. The counter 10 receives initialization by the logical data on the states of switch circuits S1- S8. Both counters 10 and 11 work on action clocks which are synchronous with each other. The counter 11 is stopped when the counter 10 delivers a carry. The output of the counter 11 is supplied to a latch circuit 12, and the signal of the circuit 12 is delivered from a buffer 13. |
