Figure 125 Write Log Ext command
This command writes a specified number of 512 byte data sectors to the specific log. The device shall interrupt for
each DRQ block transferred.
Output Parameters To The Device
Sector Count Current
The number of sectors to be written to the specified log low order, bits
(7:0).
Sector Count Previous
The number of sectors to be written to the specified log high orders,
bits (15:8). If the number of sectors is greater than the number
indicated in the Log directory, which is available in Log number zero,
the device shall return command aborted. The log transferred to the
device shall be stored by the device starting at the first sector in the
specified log.
Sector Number Current
The log to be written as described in Figure 51 Log address definition. If
the host attempts to write to a read only log address, the device shall
return command aborted.
Cylinder Low Current
The first sector of the log to be written low order, bits (7:0).
Cylinder Low Previous
The first sector of the log to be written high order, bits (15:8)
If the feature set associated with the log specified in the Sector Number register is not supported or enabled, or if the
values in the Sector Count, Sector Number or Cylinder Low registers are invalid, the device shall return command
aborted. If the host attempts to write to a read only log address, the device shall return command aborted.
