The feature register will indicate the subcommand as listed below.

Command Purpose:
This Command is used to communicate the reliability status of the device to the host at the host’s request.
If the device has not detected a threshold exceeded condition, the device sets the LBA Mid register to
4FH and the LBA High register to C2H. If the device has detected a threshold exceeded condition, the
device sets the LBA Mid register to F4H and the LBA High register to 2CH. In the current implementation,
the only threshold checked is that a fatal error has occurred.

Command Purpose:
This Command enables or disables the optional attribute autosave feature of the device. A value of 00H
in the Sec Cnt register will disable the autosave feature. A value of F1H in the Sec Cnt register will enable
the autosave feature. Currently, no action is generated by this command since there in no online
collection of data.
