Table 152 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
values are as follows:
1. 01h indicates Set Max Set Password command

register. Identify device command returns the Address which is set via this command as a default value.
If the device in Address Offset mode receives this command with the nonvolatile option, the device returns
