Table 186 Write Multiple FUA Ext Command (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.
