ATA Bus Interface and ATA Commands<br />
Hosts may assert the RESET- signal for longer than the minimum. When<br />
power is applied with RESET- asserted, the <strong>Quickview</strong> <strong>300</strong> disk media<br />
will not begin to spin up until RESET- is negated. This may reduce<br />
maximum current consumption for the overall system.<br />
5.4 REGISTER ADDRESS DECODING<br />
The <strong>Quickview</strong> <strong>300</strong> hard disk drives allow their host systems to address<br />
the full set of command and control registers as specified in clause 7 of<br />
the ATA/ATAPI-6 standard.<br />
5.5 COMMAND INTERFACE<br />
5.5.1 General Feature Set<br />

contained in a proprietary ASIC developed by Maxtor.<br />

Packet command feature set. Refer to the ATA/ATAPI-6 standard for a<br />
