10.8.33.5.1 Off-line mode

The following describes the protocol for executing a SMART EXECUTE OFF-LINE IMMEDIATE

subcommand routine (including a self-test routine) in the off-line mode.

a) The device executes command completion before executing the subcommand routine.

b) After clearing BSY to zero and setting DRDY to one after receiving the command, the device shall not set

BSY nor clear DRDY during execution of the subcommand routine.

c) If the device is in the process of performing the subcommand routine and is interrupted by any new

command from the host except a SLEEP, SMART DISABLE OPERATIONS, SMART EXECUTE

OFF-LINE IMMEDIATE, or STANDBY IMMEDIATE command, the device suspends or aborts the

subcommand routine and service the host within two seconds after receipt of the new command. After

servicing the interrupting command from the host the device may immediately re-initiate or resume the

subcommand routine without any additional commands from the host.

d) If the device is in the process of performing a subcommand routine and is interrupted by a SLEEP

command from the host, the device may abort the subcommand routine and execute the SLEEP

command. If the device is in the process of performing any self-test routine and is interrupted by a

SLEEP command from the host, the device shall abort the subcommand routine and execute the SLEEP

command.

e) If the device is in the process of performing the subcommand routine and is interrupted by a SMART

DISABLE OPERATIONS command from the host, the device shall suspend or abort the subcommand

routine and service the host within two seconds after receipt of the command. Upon receipt of the next

SMART ENABLE OPERATIONS command the device may, either re-initiate the subcommand routine or

resume the subcommand routine from where it had been previously suspended.

f) If the device is in the process of performing the subcommand routine and is interrupted by a SMART

EXECUTE OFF-LINE IMMEDIATE command from the host, the device shall abort the subcommand

routine and service the host within two seconds after receipt of the command. The device shall then

service the new SMART EXECUTE OFF-LINE IMMEDIATE subcommand.
