Abstract
An address detection circuit is formed in a pod so that the circuit generates a detection signal DET when an address signal specifying an address in the address area assigned to a newly-added circuit section is outputted from an evaluation MCU, and a disabling circuit 313 is formed in a port emulation circuit 31a so that the circuit 313 disables an input/output circuit 312 from being set to the input state by responding to the detection signal DET.
