and subcode areas in buffer RAM.

• Batch transfer function (Function for transferring the CD

main channel, C2 flag, subcode, and other data in a

single operation)

• Multi-transfer function (Function for automatically

transferring multiple block to the host in a single

operation)

• CAV audio functions

• Supports Ultra DMA modes 0, 1, and 2.
