Features
SCSI interface (includes on-chip SCAM selection register) Supports 20× speed and a 10 MBytes/s transfer rate when using 16-bit 70-ns EDO DRAM Supports 40× speed and a 10 MB/s transfer rate when using 16-bit 50-ns EDO DRAM Up to 4 M bits of buffer RAM can be used. The user can freely set up the CD main channel and the C2 flag areas in buffer RAM. Batch transfer function (Allows the CD main channel, the C2 flags, and other data to be sent in a single operation.) Multi-block transfer function (Allows multiple blocks to be sent automatically in a single operation.) Subcode buffering and CD-TEXT support
