• SET MAX UNLOCK (FR=03h)
This command requests a transfer of single sector of data from the host, and
defines the contents of SET MAX ADDRESS password. The data transferred
controls the function of this command.
The password supplied in the sector of data transferred shall be compared with the
stored password.
If the password compare fails, the device returns command aborted and
decrements the Unlock counter, and remains in the Set Max Lock state. On the
acceptance of the SET MAX LOCK command, the Unlock counter is set to a
value of five. When this counter reaches zero, then 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 will be accepted.
