3.0 ATA interface

These drives use the industry-standard ATA task file interface that supports 16-bit data transfers. It supports ATA programmed input/output (PIO) modes 0, 1, 2, 3 and 4; multiword DMA modes 0, 1 and 2; and Ultra DMA modes 0, 1, 2, 3 and 4. The drive also supports the use of the IORDY signal to provide reliable high-speed data transfers.

You can use a daisy-chain cable to connect two drives to a single AT host bus. For detailed information about the ATA interface, refer to the draft of AT Attachment with Packet Interface Extension (ATA/ATAPI-4), NCITS T13 1153D, subsequently referred to as the Draft ATA-4 Stan- dard.

3.1 ATA interface signals and connector pins

Figure 4 on page 23 summarizes the signals on the ATA interface connector that the drive supports. For a detailed description of these signals, refer to the Draft ATA-4 Standard.
