ABSTRACT:
A data processing system provides a diagnostic circuit having a scan-out function, that includes error checking. A scan-out address check code is generated by a sending unit and another scan-out address check code is generated by a receiving unit. The scan-out address check codes are compared in the sending unit, and an error in the scan-out operation can be detected.
