SET MAX UNLOCK (Features Field = 03h)
This command requests a transfer of single sector of data from the host, and
defines the contents of SET MAX ADDRESS password.
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 returns
command aborted until a power cycle.
If the password compare matches, then the device makes a transition to the Set
Max Unlocked state and all SET MAX commands will be accepted.
