*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 Section 7.1.2.
*2: The Universal model QCPU except the Q00UJCPU, Q00UCPU, and Q01UCPU.

Drive 2 type
(The bits for the drive 1 (RAM) type and drive 2 (ROM) type are fixed to "0"
in the Q00UJCPU, Q00UCPU, and Q01UCPU.)
• Drive 1 capacity is stored in 1 k byte units.
• (Empty capacity after format is stored.)
• Drive 2 capacity is stored in 1 k byte units.
• The use conditions for memory card are stored as bit patterns .
(In use when ON)
• The significance of these bit patterns is indicated below:
b0 : Boot operation (QBT) b8 : Not used
b1 : Parameters (QPA) b9 : CPU fault history (QFD)
b2 : Device comments (QCD) b10 : Not used
b3 : Device initial value (QDI) b11 : Local device (QDL)
b4 : File register R (QDR) b12 : Not used
b5 : Sampling trace (QTD) b13 : Not used
b6 : Not used b14 : Not used
b7 : Not used b15 : Not used
