    Write CDP 2.45 Write CDP (E3h) Operation Code is (E3h). Transfer Length is the number of bytes of CDP command data to be sent. This command sends alphanumeric Player Control commands to the drive. The drive returns the command status after the player control command is transferred to the drive controller chip. A GOOD status indicates only that the command was syntactically correct.

    2.46 Read CD-DA (D8h) IMPORTANT: This command applies only to models DRM-602X, DRM-624X, and the DR-U Series drives. Operation Code is (D8h). The READ CD-DA command requests that the drive transfer CD-DA data and/or Sub Code data. The Starting Logical Block Address specifies the block where the READ operation begins. The definition of the starting logical block address is as follows: Starting Logical Block Address = (M-Ms) * 60 * 75 + (S-Ss) * 75 + (F-Fs) (M, S, F) = absolute MSF address of the requested starting logical block...
  • Page 171 CD-ROM SCSI-2 COMMAND REFERENCE MANUAL VERSION 3.1 (OB-U0077C) NOTES: 1) The CD-DA block lengths are totally irrelevant to the logical block length set by the Mode Select(6) command. This command would not change the block length field in the MODE SELECT command.

Starting M, S, F Fields indicates the absolute MSF address where the operation begins. Ending M, S, F Fields indicates the absolute MSF address where the operation ends. If the ending address is smaller than the starting address, check condition will be returned.

Operation Code is (DFh) Transfer Length indicates the number of contiguous sub-code frames to be transferred. Each sub-code frame consists of 96-byte data. Read All Subcode command directs the target to transfer real-time sub-code data (P-W) to the initiator while the audio is being played.

    At times, the two subsystems may be operating independently. In addition to the normal audio commands, the CD-ROM drives support the Pioneer Laser Disc Player control commands. These alphanumeric mnemonics may be sent to the drive using the vendor-unique command WRITE CDP (Character Device Player). The WRITE READ CDP command strings are passed through the controller directly to the reader.
