Table 31: Supported Security Commands
This command requests transfer of single sector of data from host which
contains Control Word 0 (to select Master or User Password compare),
and Password 1-16 (32 Bytes). If password matches password previously
saved by the card, the card disables lock mode. Command does not
change Master password which may be reactivated later by setting a
User password.
This command shall be issued immediately before SECURITY ERASE
UNIT command to enable device erasing and unlocking. Command
prevents accidental erase of card.
This command requests transfer of single sector of data with control and
password. If password is matched, command executes. The SECURITY
ERASE PREPARE command shall be completed immediately prior to this
command.
This command sets the card to Frozen mode in which the following
commands are disabled: 1) Security Set Password, 2) Security Unlock, 3)
Security Disable Password, and 4) Security Erase Unit. Frozen mode is
disabled by power off or hardware reset. If Security Freeze Lock is issued
when card is in Frozen mode, command executes and card remains in
Frozen mode.
This command requests transfer of single sector of data with Control and
Passwords. Depending on the content of the Control Word, the User or
Master Password, and the High or Maximum Security Level is set.
This command requests transfer of single sector of data from host. If
identifier bit is set to Master and the device is in high security level, then
the password supplied shall be compared with the stored Master
password. If card is in maximum security level, then the unlock command
shall be rejected. If the identifier bit is set to user, then card compares the
supplied password with the stored User password. If the password
compare fails then card returns command aborted to host and
decrements the unlock counter. Counter is initially set to five and is
decremented for each password mismatch when Security Unlock is
issued and card is locked. Once this counter reaches zero, SECURITY
UNLOCK and SECURITY ERASE UNIT commands are command
aborted until after a power-on reset or a hardware reset is received.
SECURITY UNLOCK commands issued when the device is unlocked
have no effect on the unlock counter.
