Abstract
PURPOSE:To decrease the number of terminals and to realize a compact size together with reduction of the cost for an action mode switching device, by securing the selective processing between an input/storage state and an output state of an action mode based on the state of a single input/output terminal. CONSTITUTION:When an action mode is set an input/output selection terminal program selection terminal 15 has a logic level '0'. In this case, the terminals 2, 3 and 4 are used as input terminals and connected to a control power supply VDD via a pull-up resistance 9. Furthermore the terminals 2-4 are grounded via contacts 8a-8c of an action mode setting switch 8. When a 1-chip microcomputer 1 where the action mode data is already stored is installed, the logic level 1 is supplied to the terminal 15 of the computer 1. Then the terminals 2 and 3 are used as output terminals and connected to each part of a controller.
