Abstract
PURPOSE: To prevent the error of the control signal, by giving a checking to the control signal based on the interface rule.
CONSTITUTION: In case the two units are units are controlled by the signal lines AWD of the control signal, the signals shown by the symbols 2W10 are significant in terms of the interface rule. While the states shown by 2AW2F are defined insignificant in terms of the interface rule. Thus the signals are not those which are generated in the normal state. Accordingly, the error of the control signal can be prevented by giving a checking to the generation of the signals 2AW2F. In this connection, the inverters N1WN9 are combined with the gates 3AW3F to form the checking circuit, and the signals of the signal lines AWD are supplied to the checking circuit. As a result, the output is produced from the gate OP when the signals 2AW2F are produced. Through such checking, the error of the control signal can be prevented.
