Abstract
PURPOSE: To facilitate the detection of drive circuits for a bus that are simultaneously in ON, by connecting resistances among a bus line and the drive circuits, and by measuring the voltage drop thereof.
CONSTITUTION: When the output of a drive circuit 37 for a bus keeps a condition of O, a drive circuit 31 for the bus transfers the output to a line 34 for the bus only when it is selected. In this case, currents flow through the circuit 37 from the output of the circuit 31, voltage drops at resistances 33, 35 and the voltage drop is detected by means of comparators 32, 36 and displayed. Thus, the drive circuit under a trouble condition can easily be detected.
