Signals on the ATA interface are assigned to connector pins according to Table A.1
and A.8 of the ATA/ATAPI-6 standard. The signaling protocol complies with section
9 and signal timing complies with section 10 of the standard.
The Maxtor D540X-4K hard disk drives support all Ultra DMA Data Transfer modes
of ATA/ATAPI-6. In Mode 5, it can send and receive data at the full 100 MB/s
transfer rate.
Hosts may assert the RESET- signal for longer than the minimum. When power is
applied with RESET- asserted, the Maxtor D540X-4K disk media will not begin to
spin up until RESET- is negated. This may reduce maximum current consumption
for the overall system.
