Interface description

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 0–2. The

drive also supports the use of the IORDY signal to provide reliable high-speed data transfers.

For detailed information about the CompactFlash interface, refer to CF+ and CompactFlash Spec Rev 2.0.
