Figure 48 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
LBA Low Current	Identify Device information.
	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.
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.
