PROBLEM TO BE SOLVED: To provide a code inspecting method and circuit capable of performing CRC inspection to a plurality of generation polynomials by using CRC bits as the termination information of reception data. SOLUTION: In this code inspecting method for executing an arithmetic operation to a data polynomial by a generation polynomial whose order is different, and for inspecting a signal obtained by inverting the sequence of the bits of the remainder, and adding it to the data polynomial, delay elements for the maximum order of the generation polynomial are disposed in the pre- stage of the input to a code generator by the generation polynomial, and the order of the generation polynomial is switched, and the number of stages of the delay elements is set so as to be the same as the order, and information from the delay elements is reversely sequenced, and compared with signals from the code generator for inspection.
