This command is used to pre-erase and condition data sectors in advance of a Write without Erase or Write
Multiple without Erase command. There is no data transfer associated with this command but a Write Fault error
status can occur.
This command causes the card to complete writing data from its cache. The card returns status with RDY=1 and
DSC=1 after the data in the write cache buffer is written to the media. If the Compact Flash Storage Card does not
support the Flush Cache command, the Compact Flash Storage Card shall return command aborted.
This command writes the desired head and cylinder of the selected drive with a vendor unique data pattern
(typically FFh or 00h). To remain host backward compatible, the CompactFlash Storage Card 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 CompactFlash Storage Card. If LBA=1 then the number of
sectors to format is taken from the Sec Cnt register (0=256). The use of this command is not recommended.
