Appendix 4 SPECIAL REGISTER LIST
(5) Memory card
*1: When the Q2MEM-8MBA is used, value stored in the special register SD603 differs depending on the combination of the serial number of the High
Performance model QCPU and the manufacture control number of the ATA card.
For details, refer to QCPU User's Manual (Hardware Design, Maintenance and Inspection).
*2: The Universal model QCPU except the Q00UJCPU, Q00UCPU, and Q01UCPU.
