Figure 127 Write Multiple Command (C5h)
The Write Multiple command transfers one or more sectors from the host to the device, then the data is written to
the disk media.
Command execution is identical to the Write Sectors 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
The number of continuous sectors to be transferred. If zero is specified, then 256 sectors
will be transferred.
LBA Low
The sector number of the first sector to be transferred. (L=0)
In LBA mode, this register contains LBA bits 0 - 7. (L=1)
LBA
High/Mid
The cylinder number of the first sector to be transferred. (L=0)
In LBA mode, this register contains LBA bits 8 - 15 (Mid), 16 - 23 (High). (L=1)
H
The head number of the first sector to be transferred. (L=0)
In LBA mode, this register contains LBA bits 24 - 27. (L=1)
Input Parameters From The Device
Sector Count
The number of requested sectors not transferred. This will be zero, unless an
unrecoverable error occurs.
LBA Low
The sector number of the last transferred sector. (L=0)
In LBA mode, this register contains current LBA bits 0 - 7. (L=1)
LBA
High/Mid
The cylinder number of the last transferred sector. (L=0)
In LBA mode, this register contains current LBA bits 8 - 15 (Mid), 16 - 23 (High).
(L=1)
H
The head number of the last transferred sector. (L=0)
In LBA mode, this register contains current LBA bits 24 - 27. (L=1)
