Table 127 Write DMA Command (CAh/CBh)

The Write DMA command transfers one or more sectors of data from the host to the device, then the data is written to the disk media.

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	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)
R	The retry bit, but this bit is ignored.
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)
