Standard ATA Command Summary
This section provides a summary of each supported ATA command.
Check Power Mode (98h or E5h)
The Check Power Mode command allows the host to determine the current power mode of the
device. The Check Power Mode command shall not cause the device to change power or affect the
operation of the Standby timer.
Download Microcode (92h)
The command allows the host to alter the microcode of the device. The data transferred using the
Download Microcode command is vendor-specific. All transfers are an integer multiple of the sector
size. The size of the data transfer is determined by the contents of the LBA Low register and the
Sector Count register. The LBA Low register will extend the Sector Count register to create a 16-bit
sector count value. The LBA Low register will be the most significant eight bits and the Sector Count
register will be the least significant eight bits. A value of zero in the LBA Low and Sector Count
registers specify that no data is to be transferred. This allows transfer sizes from 0 bytes to
33,553,920 bytes, in 512-byte increments. The Features register will determine the effect of the
Download Microcode command.
Erase Sector (C0h)
This command will pre-erase and condition the data sectors in advance.
Execute Drive Diagnostic (90h)
This command performs the internal diagnostic tests implemented by the controller.
Flush Cache (E7h)
This command is used by the host to request the device to flush the Write cache. If there is data in
the Write cache, that data shall be written to the media. The command will not indicate completion
until the data is flushed to the media or an error occurs. If the device supports more than 28 bits of
addressing, this command shall attempt to flush all the data in the cache. If the Write cache is
disabled or is not present, the device will indicate completion without error. The command is
mandatory for devices not implementing the PACKET feature set.
Flush Cache Extended (EAh)
This command is used by the host to request the device to flush the Write cache. If there is data in
the Write cache, that data shall be written to the media. The command will not indicate completion
until the data is flushed to the media or an error occurs. If the Write cache is disabled or is not present,
the device will indicate completion without error. This command is mandatory for devices that
implement the 48-bit Address feature set.
