A scan operation executing system includes a command decoding unit and a scan mode setting unit. The command decoding unit is initialized together with a diagnostic control unit in accordance with a diagnostic activation signal from a diagnostic processor, outputs a reset signal in response to a diagnostic command for a scan operation execution request subsequent to the diagnostic activation signal, and outputs a reset signal in response to a diagnostic command for a scan mode reset request. The scan mode setting unit is set by a set signal from the command decoding unit to supply a scan mode signal to a processing unit of a main processor and is reset by the reset signal to disconnect the scan mode signal. |
