Abstract

PURPOSE:To detect three kinds of status from one status signal line, by using output from two gates and the output from a clock detection circuit. CONSTITUTION:The titled circuit is constituted of an information input terminal 10 to which information is inputted, the clock detection circuit 12 to detect whether or not the information inputted from the information input terminal 10 is a clock, a first gate 13 to receive the output 3 of the clock detection circuit 12 on one side of the input and the information inputted from the information input terminal 10 on the other side of the input, and a second gate 14 to receive the output 3 of the clock detection circuit 12 on one side of the input and the inversion signal of the information inputted from the information input terminal 10 on the other side of the input. In such a way, it is possible to take out signals representing the three kinds of status of input information from the clock detection circuit 12, and the first and second gates 13 and 14.
