Host Commands | Fujitsu MHU2100AT specification

	5.3 Host Commands
Log address:	Log number of the log to be written
Sector offset:	First log sector subject to the data transfer
Sector count:	Number of sectors to be written to the specified log

If the device does not support this command, the device shall return the Command Aborted error.

If the Log address value, the Sector count value, or the Sector offset value is invalid, the device shall return the Command Aborted error.
