12.50 Write Multiple (C5h)
Table 120: Write Multiple (C5h)
The Write Multiple command transfers one or more sectors from the host to the device. The data is then written to
the disk media.
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.
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
This indicates the number of continuous sectors to be transferred. If the Sector Count of
zero is specified, 256 sectors will be transferred.
zero is specified, 256 sectors will be transferred.
LBA Low
This indicates the sector number of the first sector to be transferred. (L = 0)
In LBA mode this register contains the LBA bits 0–7. (L = 1)
LBA High/MId
This indicates the cylinder number of the first sector to be transferred. (L = 0)
In LBA mode this register contains the LBA bits 8–15 (Mid) and bits 16–23(High).(L = 1)
H
This indicates the head number of the first sector to be transferred. (L = 0)
In LBA mode this register contains the LBA bits 24–27. (L = 1)
Input parameters from the device
Sector Count
This indicates the number of requested sectors not transferred. The Sector Count will be
zero, unless an unrecoverable error occurs.
zero, unless an unrecoverable error occurs.
LBA Low
This indicates the sector number of the last transferred sector. (L = 0)
In LBA mode this register contains current the LBA bits 0–7. (L = 1)
LBA High/Mid
This indicates the cylinder number of the last transferred sector. (L = 0)
In LBA mode this register contains the current LBA bits 8–15 (Mid) and bits 16–23
(High). (L = 1)
(High). (L = 1)
H
This indicates the head number of the last transferred sector. (L = 0)
In LBA mode this register contains current the LBA bits 24–27. (L = 1)
