Set Max ADDRESS (F9h)
The device regards as Set Max Address command, if this command is immediately preceded by a Read Native
Max Address command. The device receives this command without a prior Read Native Max Address command,
the device regards as Set Max security extensions command according to feature register value. Valid features
