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. 154/167
