Table 262 Write Multiple FUA Ext Command (CEh)
The Write Multiple Ext command transfers one or more sectors from the host to the device, and then the data is
written to the disk media. This command provides the same function as the Write Multiple Ext command except that
the transferred data shall be written to the media before the ending status for this command is reported also when
write caching is enabled.
Command execution is identical to the Write Sector(s) Ext command except that an interrupt is generated for each
block (as defined by the Set Multiple command) instead of for each sector. The sectors are transferred through the
Data Register 16 bits at a time.
Output Parameters To The Device
Sector Count Current
The number of continuous sectors to be transferred low order, bits (7:0)
Sector Count Previous
The number of continuous sectors to be transferred high order, bits (15:8). If zero
is specified in the Sector Count register, then 65,536 sectors shall be transferred.
Sector Number Current
LBA (7:0).
Sector Number Previous
LBA (31:24).
Cylinder Low Current
LBA (15:8).
Cylinder Low Previous
LBA (39:32).
Cylinder High Current
LBA (23:16).
Cylinder High Previous
LBA (47:40).
Input Parameters From The Device
Sector Number (HOB=0)
LBA (7:0) of the address of the first unrecoverable error.
Sector Number (HOB=1)
LBA (31:24) of the address of the first unrecoverable error.
Cylinder Low (HOB=0)
LBA (15:8) of the address of the first unrecoverable error.
