LBA Mid	na or 4Fh
LBA High	na or C2h
Device	obs	na	obs	DEV	na		na		na		na
Status	BSY	DRDY	DF	na	DRQ		na		na		ERR

LBA Mid -

na when the subcommand specified an off-line routine including an off-line self-test routine. 4Fh when the subcommand specified a captive self-test routine that has executed without failure.

LBA High -

na when the subcommand specified an off-line routine including an off-line self-test routine. C2h when the subcommand specified a captive self-test routine that has executed without failure.

Device register –

DEV shall indicate the selected device.

Status register -

BSY shall be cleared to zero indicating command completion.

DRDY shall be set to one.

DF (Device Fault) shall be cleared to zero.

DRQ shall be cleared to zero.

ERR shall be cleared to zero.

Error Outputs:

Register	7	6	5	4	3	2		1		0
Error	na	na	na	IDNF	na	ABRT		na		na

LBA Low	na
LBA Mid	na or 4Fh or F4h
LBA High	na or C2h or 2Ch
Device	obs	na	obs	DEV	na
Status	BSY	DRDY	DF	na	DRQ		na		na		ERR

Error register –

IDNF shall be set to one if SMART data sector’s ID field could not be found.

ABRT shall be set to one if this command is not supported or if the input register values are invalid. ABRT may be set to one if the device is not able to complete the action requested by the command.

LBA Mid register –

na when the subcommand specified an off-line routine (including an off-line self-test routine).

4Fh when the subcommand specified a captive self-test routine and some error other than a self-test routine failure occurred (i.e., if the sub-command is not supported or register values are invalid)

F4h when the subcommand specified a captive self-test routine which has failed during execution.

LBA High register –

na when the subcommand specified an off-line routine (including an off-line self-test routine).

2Ch when the subcommand specified a captive self-test routine which has failed during execution.

C2h when the subcommand specified a captive self-test routine and some error other than a self-test routine failure occurred (i.e., if the sub-command is not supported or register values are invalid)

Device register -
