Abstract: A register read circuit reads out register values of X (natural number) registers corresponding to selection register numbers. The registers are each assigned to a unique register number. Register numbers that correspond to the X registers to be selected among the registers are given to the register read circuit as the selection register numbers' The register read circuit includes register value selection circuits each of which selects the register value of one of the X registers corresponding to the register numbers associated with remainders of modulo of the register numbers by Y, which is a natural number larger than or equal to X. Each of the selection circuits selects and outputs one of register values from the registers in response to a selection control input based on the given register number, the register value selection circuits being correspondent to the remainders.

Abstract: When a test mode signal is rendered active by a signal given from an external terminal, a CPU reads and runs various self-testing programs stored in a ROM. When any of the test programs comes to a process of testing a security circuit, a security test signal is rendered active and when a predetermined address is accessed then, a selector is switched to a register side by the output signal of an AND circuit of a test circuit. An illegitimate instruction, for example, is set in the register and is given to the CPU. Whether the security circuit has failure is determined by checking if an illegitimate access detection signal is output when the CPU executes the illegitimate instruction.
