Abstract
In a logic unit provided with a plurality of internal registers, an internal memory and a combinational circuit, such as an arithmetic unit, at least one of the plurality of internal registers is arranged to be scanned in and out. During diagnosis, when executing an instruction which makes reference to the internal memory, the register that can be scanned in and scanned out is used in place of the internal memory for diagnosing the combinational circuit.
