Table 133 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) |
