Figure 106 Write Multiple Ext Command (39h)
The Write Multiple Ext 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 Sector(s) Ext 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 Current | The number of continuous sectors to be transferred low order, bits (7:0) |
Sector Count Previous | The number of continuous sectors to be transferred high order, bits (15:8). If zero is |
LBA Low Current | specified in the Sector Count register, then 65,536 sectors shall be transferred. |
LBA (7:0). | |
LBA Low Previous | LBA (31:24). |
LBA Mid Current | LBA (15:8). |
LBA Mid Previous | LBA (39:32). |
LBA High Current | LBA (23:16). |
LBA High Previous | LBA (47:40). |
Input Parameters From The Device | |
LBA Low (HOB=0) | LBA (7:0) of the address of the first unrecoverable error. |
LBA Low (HOB=1) | LBA (31:24) of the address of the first unrecoverable error. |
LBA Mid (HOB=0) | LBA (15:8) of the address of the first unrecoverable error. |
LBA Mid (HOB=1) | LBA (39:32) of the address of the first unrecoverable error. |
LBA High (HOB=0) | LBA (23:16) of the address of the first unrecoverable error. |
LBA High (HOB=1) | LBA (47:40) of the address of the first unrecoverable error. |
