11.2.1.39 Write-Multiple-Without-Erase - CDH
This command is similar to the Write-Multiple command with the exception that an implied Erase before
Write operation is not performed. The sectors should be pre-erased with the Erase-Sector(s) command
before this command is issued. If the sectors are not pre-erased with the Erase-Sector(s) command, a
normal Write-Multiple operation will occur.
11.2.1.40 Write-Sector(s) - 30H or 31H
This command writes from 1 to 256 sectors as specified in the Sector Count register. A sector count of
zero requests 256 sectors. The transfer begins at the sector specified in the Sector Number register.
When this command is accepted, the ATA Flash Disk Controller sets BSY, then sets DRQ and clears
BSY, then waits for the host to fill the sector buffer with the data to be written. No interrupt is generated
to start the first host transfer operation. No data should be transferred by the host until BSY has been
cleared by the host.
For multiple sectors, after the first sector of data is in the buffer, BSY will be set and DRQ will be
cleared. After the next buffer is ready for data, BSY is cleared, DRQ is set and an interrupt is generated.
When the final sector of data is transferred, BSY is set and DRQ is cleared. It will remain in this state
until the command is completed at which time BSY is cleared and an interrupt is generated.
If an error occurs during a write of more than one sector, writing terminates at the sector where the
error occurs. The Command Block registers contain the cylinder, head and sector number of the sector
where the error occurred. The host may then read the command block to determine what error has
occurred, and on which sector.
