12.53 Writer Multiple FUA Ext (CEh)
The Write Multiple Ext command transfers one or more sectors from the host to the device, and then the data is
written to the disk media. This command provides the same function as the Write Multiple Ext command except
that the transferred data shall be written to the media before the ending status for this command is reported also
when write caching is enabled.
Command execution is identical to the Write Sector(s) Ext command except that an interrupt is generated for each
block (as defined by the Set Multiple command) instead of for each sector. The sectors are transferred through the
Data Register 16 bits at a time.
