29. SET MAX LOCK ( code: F9h): This command sets the device into Set Max Locked state. After this
command is completed any other Set Max commands except Set Max Unlock and Set Max Freeze Lock are
rejected. The device remains in this state until a power cycle or the acceptance of a Set Max Unlock or Set
Max Freeze Lock command.
30. SET MAX UNLOCK (code: F9h): This command requests a transfer of a single sector of data from the
host. Password data Table defines the content of this sector of information. The password supplied in the
sector of data transferred shall be compared with the stored SET MAX password. If the password compare
fails, then the device returns command aborted and decrements the unlock counter. On the acceptance of the
Set Max Lock command, this counter is set to a value of five and shall be decremented for each password
mismatch when Set Max Unlock is issued and the device is locked. When this counter reaches zero, then the
Set Max Unlock command shall return command aborted until a power-cycle. If the password compare
matches, then the device shall make a transition to the Set Max Unlocked state and all SET MAX commands
shall be accepted.
