Figure 158. Write Multiple Command (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.
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.
Output parameters to the device
Sector Count The number of continuous sectors to be transferred. If zero is specified, 256
sectors will be transferred.
Sector Number The sector number of the first sector to be transferred. (L=0)
In LBA mode this register contains LBA bits 0 - 7. (L=1)
Cylinder High/Low 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)
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.
