6.1.36 Write-Buffer – E8H
The Write-Buffer command enables the host to overwrite contents of the Device sector buffer with any
data pattern desired. This command has the same protocol as the Write-Sector(s) command and
transfers 512 byes.
6.1.37 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 device 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 device 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.
