When the ODD receives this command, it transfers device parameter information to the host. It accepts this command even if in standby mode.

Table 4.19 lists the transfer data format. The reserved word indicates a value of 0.

The transfer byte length is 512 bytes.

One-word information uses DD15 as MSB (Most Significant Bit) and DD0 as LSB (Least Significant Bit).

For ASCII character information such as base serial number, firmware version number, and product number, the first character code in the string uses word 1, DD15 to 8; the second character code uses word 1, DD7 to 0; the third character code uses word 2, DD15 to 8; and so on.
