Abstract
To include an FCS code calculation unit to calculate a first code that is an FCS code of a received frame, an FCS check unit to compare the first code with a second code that is an FCS code stored in the received frame, and to output a first comparison result indicating a match or no match between two codes, an inverse FCS check unit to compare the first code with a third code obtained by inverting each bit of the second code, and to output a second comparison result indicating a match or no match between two codes, an error determination unit to determine an error state of the received frame, and an FCS update unit to update, if the second comparison result indicates no match, the second code with a fourth code obtained by inverting each bit of the first code.
