immediately preceded by a READ NATIVE MAX ADDRESS command, it shall be interpreted as a SET MAX
ADDRESS command.
This command requests a transfer of a single sector of data from the hostTable 10.8-7 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.

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.
