6.1.27 Write-DMA – CAH or CBH
This command executes in a similar manner to Write-RITE Sector(s) except for the following:
-
- Data transfers are qualified by DMARQ and are performed by the DMA channel
- The compact flash card issues only one interrupt per command to indicate that data transfer has
terminated and status is available.
During the execution of a Write-RITE DMA command, the compact flash card shall provide status of the
BSY bit or the DRQ bit until the command is completed. At command completion, the command block
registers contain the cylinder, head and sector number (LBA) of the last sector read.
If an error occurs after the attempted write of a transferred sector, the command is terminated and
subsequent blocks are not transferred. The command block registers contain the cylinder, head and
sector number of the sector where the error occurred and the Sector Count register contains the residual
number of sectors for successful completion of the command.
For Ultra-DMA mode, if a CRC error is detected during transfer, the ICRC and ABRT bits of the Error
register are set at the end of the command.
6.1.28 Write-Multiple – C5H
This command is similar to the Write-Sectors command. The compact flash card 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
