Maxtor 300 Register Address Decoding, Command Interface, General Feature Set, Supported Commands

ATA Bus Interface and ATA Commands

Hosts may assert the RESET- signal for longer than the minimum. When power is applied with RESET- asserted, the Quickview 300 disk media will not begin to spin up until RESET- is negated. This may reduce maximum current consumption for the overall system.

5.4REGISTER ADDRESS DECODING

The Quickview 300 hard disk drives allow their host systems to address the full set of command and control registers as specified in clause 7 of the ATA/ATAPI-6 standard.
