6.1.38 Long –32H or 33H
This command is similar to the Write Sector(s) command except that it writes 516 bytes instead of 512
bytes. Only single sector Write Long operations are supported. The transfer consists of 512 bytes of data
transferred in word mode followed by 4 bytes of ECC transferred in byte mode. Because of the unique
nature of the solid-state device, the four bytes of ECC transferred by the host may be used by the device.
The device may discard these four bytes and write the sector with valid ECC data. This command has the
same protocol as the Write Sector(s) command. Use of this command is not recommended.
6.1.39 Write-Multiple – C5H
This command is similar to the Write-Sectors command. The Device sets BSY within 400 ns of accepting
the command. Interrupts are not presented on each sector but on the transfer of a block which contains
the number of sectors defined by Set-Multiple. Command execution is identical to the Write-Sectors
operation except that the number of sectors defined by the Set-Multiple command is transferred without
intervening interrupts.
DRQ qualification of the transfer is required only at the start of the data block, not on each sector. The
block count of sectors to be transferred without intervening interrupts is programmed by the Set-Multiple
Mode command, which must be executed prior to the Write-Multiple command.
When the Write-Multiple command is issued, the Sector Count register contains the number of sectors
(not the number of blocks or the block count) requested. If the number of requested sectors is not evenly
divisible by the sector/block, as many full blocks as possible are transferred, followed by a final, partial
block transfer. The partial block transfer is for n sectors, where: n = remainder (sector count/block count).
If the Write-Multiple command is attempted before the Set-Multiple-Mode command has been executed or
when Write-Multiple commands are disabled, the Write-Multiple operation will be rejected with an aborted
command error.
Errors encountered during Write-Multiple commands are posted after the attempted writes of the block or
partial block transferred. The Write command ends with the sector in error, even if it is in the middle of a
block. Subsequent blocks are not transferred in the event of an error. Interrupts are generated when DRQ
is set at the beginning of each block or partial block.
