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 multiword DMA mode 2, according

to 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.
