AC Electrical Characteristics
ATA Timing Characteristics
The ATA interface supports ATA PIO modes 0, 3, and 4, Ultra
DMA modes 2, 3, and 4, and multi-word DMA mode 2, per the
ATA/ATAPI 6 Specification. The highest enabled transfer rate
common to both the AT2LP and the attached mass storage
device is used. The AT2LP automatically determines the
transfer rates during drive initialization based upon the values
in the AT2LP configuration space and the data reported by the
drives in response to an IDENTIFY DEVICE command.
USB Transceiver Characteristics
Complies with the USB 2.0 specification for full- and
high-speed modes of operation.
