Table 130 Write DMA FUA Ext Command (3Dh)

The Write DMA FUA Ext command transfers one or more sectors of data from the host to the device, then the data is written to the disk media. This command provides the same function as the Write DMA Ext command except that the transferred data shall be written to the media before the ending status for this command is reported also when write caching is enabled.

The sectors of data are transferred through the Data Register 16 bits at a time.

The host initializes a slave-DMA channel prior to issuing the command. Data transfers are qualified by DMARQ and are performed by the slave-DMA channel. The device issues only one interrupt per command to indicate that data transfer has terminated and status is available.

If an uncorrectable error occurs, the write will be terminated at the failing sector

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 0000h in

 

the Sector Count register is specified, then 65,536 sectors will be transferred.

LBA Low Current

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).
