Table 71 Read FPDMA Queued Command (60h)
The Read FPDMA Queued command reads one or more sectors of data from disk media, then
transfers the data from the device to the host.
If an uncorrectable error occurs, the read will be terminated at the failing sector.
Output Parameters To The Device
Feature Current The number of sectors to be transferred low order, bits (7:0)
Feature Previous The number of sectors to be transferred high order, bits (15:8)
T TAG value. It shall be assigned to be different from all other queued commands.
The value shall not exceed the maximum queue depth specified by the Word 75 of the
Identify Device information.
LBA Low Current LBA (7:0)
LBA Low Previous LBA (31:24)
LBA Mid Current LBA (15:8)
LBA Mid Previous LBA (39:32)
LBA High Current LBA (23:16)
LBA High Previous LBA (47:40)
F FUA bit. When the FUA bit is set to 1, the requested data is always retrieved from
the media regardless of whether the data are held in the sector buffer or not. When
the FUA bit is set to 0, the data may be retrieved from the media or from the cached
data left by previously processed Read or Write commands.
P Priority bit. When the Priority bit is set to 1, the device attempts to provide better
quality of service for the command than normal priority commands.
Input Parameters From The Device
LBA Low (HOB=0) LBA (7:0) of the address of the first unrecoverable error.
LBA Low (HOB=1) LBA (31:24)of the address of the first unrecoverable error.
LBA Mid (HOB=0) LBA (15:8)of the address of the first unrecoverable error.
LBA Mid (HOB=1) LBA (39:32)of the address of the first unrecoverable error.
LBA High (HOB=0) LBA (23:16)of the address of the first unrecoverable error.
LBA High (HOB=1) LBA (47:40)of the address of the first unrecoverable error.
