PURPOSE:To easily achieve the saving in the input and output pins of controller and the multi-functions, by controlling one display selection and contol terminal, depending on the radio operation, automatic tuning and radio frequency display switch operation. CONSTITUTION:The radio receivers 1 to 7 performing the numeric display for frequency, and the numeric display section 11 incorporating the clock function are commonly used. The circuit 26 in which the clock display is given for priority with the logical sum between the output of the control logic circuit 9 having one display selection input terminal and two functional output terminals and the output of the radio power supply and the radio display selection switch is provided. Thus, the saving in the input and output pins of controller and multifunctions can easily be achieved. |
