Figure 108. 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 trans-
ferred through the Data Register 16 bits at a time.
Input Parameters From The Device
The head number of the first sector to be transferred. (L=0)
In LBA mode, this register contains LBA bits 24 - 27. (L=1)
H
The cylinder number of the first sector to be transferred. (L=0)
In LBA mode, this register contains LBA bits 8 - 15 (Low), 16 - 23 (High).
(L=1)
Cylinder High/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)
Sector Number
The number of continuous sectors to be transferred. If zero is specified, then
256 sectors will be transferred.
Sector Count
