4.0 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 0–4; multiword DMA modes 0–2, and Ultra DMA modes 0–5. 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-6), NCITS

T13 1410D, subsequently referred to as the Draft ATA-6 Standard.

4.1 ATA interface signals and connector pins

Figure 1 on page 22 summarizes the signals on the ATA interface connector that the drive supports. For a

detailed description of these signals, refer to the Draft ATA-6 Standard.
