10.8.19 Write DMA (CAh/CBh)

COMMAND CODE		1 1 0 0 1 0 1 X	REGISTER
	REGISTER SETTING		NORMAL COMPLETION
DR	drive no.		no change
CY	starting cylinder		last possible
HD	starting head		last possible
SN	starting sector		last possible
SC	no. of sector to write		00H
FT			no change
LBA	staring address		last address

This command is basically identical to Sector command except following differences.

•Host initialize slave-DMA channel before issuing command.

-Data transfer is initiated by DMARQ and handled by slave-DMA channel in the host.

-Drive issue only one interrupt at the completion of each command to show the status is valid after data transfer.

During DMA transfer phase, either BSY or DRQ is set to 1.

When a command is completed, CY, HD, SN register (LBA register) shows the sector transferred the latest.

If the drive detects unrecoverable error, the drive terminates the command and CY, HD, SN register (LBA register) shows the sector where error has occurred.
