を特徴とするデータ異常検出回路。Of the signals of values before and after the data that are continuously sent on the data transfer line, there is a register for storing the data that is clocked -1 clock earlier or the data that is currently being clocked. (Among the signals with values before and after the data, the data currently being sent on the data transfer line is compared with the data stored in the register one clock ago, and if they do not match, the a comparator for updating the contents of the register by replacing it with the current data; and a comparator for updating the contents of the register by replacing the contents with the current data; The device is configured to include a counter for counting the number of times that the values of signals before and after data that are continuously sent do not change, and for sending out an alarm signal when the number of counts reaches a specified value. Characteristic data anomaly detection circuit.
