This command causes the ATA Flash Disk Controller to complete writing data from its cache. The ATA
Flash Disk Controller then clears BSY and generates an interrupt.

This command is accepted for host backward compatibility. The ATA Flash Disk Controller expects a
sector buffer of data from the host to follow the command with the same protocol as the Write-Sector(s)
command although the information in the buffer is not used by the ATA Flash Disk Controller. The use of
this command is not recommended.

The Identify-Drive command enables the host to receive parameter information from the ATA Flash Disk
Controller. This command has the same protocol as the Read-Sector(s) command. The parameter
words in the buffer have the arrangement and meanings defined in Table 11-4. All reserved bits or
words are zero. Table 11-4 gives the definition for each field in the Identify-Drive information.
