and the current security level is high, the password is compared with the stored Master password. If
the device is in maximum security level then the unlock shall be rejected. If the Identifier bit is set to
User, then the device shall compare the supplied password with the stored User password. If the
password comparison fails, the device shall abort the command and report a decrease in the
incremental value in the unlock counter.
Seek (70h, 7Fh)
This command is effectively a NOP command to the SSD although it does perform a range check.
Set Features (EFh)
This command is used by the host to establish or select certain features supported by the drive. When
the SSD receives this command, it sets BSY, checks the contents of the Features register, applies
changes as necessary, clears BSY and generates an interrupt. If the value in the register does not
represent a feature supported by the drive, the command is canceled with the Abort Error condition.
Set Multiple Mode (C6h)
This command enables the SSD to perform multiple Read and Write operations and establishes the
block count for these commands.
Set Sleep Mode (99h or E6h)
This is the only command that allows the host to configure the drive for Sleep Mode. When the drive
is set to Sleep Mode, the SSD clears the BSY line and issues an interrupt. The card enters Sleep
Mode and the hardware or software must be reset to activate the drive.
Sleep (E6h)
This command is mandatory for devices that implement the Power Management feature set. The
command will cause the device to enter Sleep mode. The device will not power-on in Sleep mode nor
remain in Sleep mode following a reset sequence. The method used to deactivate Sleep mode is
transport specific. The Power Management feature set is mandatory for devices that do not
implement the PACKET Command set. This command is mandatory when power management is not
implemented by the PACKET Command set device.
SMART (B0h)
See
SMART
Support.
Standby (96h or E2h)
This command will configure the drive for Standby Mode. If the Sector Count Register is a value other
than 0H, an Auto Power Down is enabled and when the drive returns to Idle Mode, the timer starts a
countdown. The time is set in the Sector Count Register.
