(ER) Error information
• SET MAX FREEZE LOCK (FR = 04h)
The Set MAX FREEZE LOCK command sets the device to SET_MAX_Frozen
state.
After the device made a transition to the Set Max Freeze Lock state, the following
SET MAX commands are rejected, then the device returns command aborted:
• SET MAX ADDRESS
• SET MAX SET PASSWORD
• SET MAX LOCK
• SET MAX UNLOCK
If the Device is in the SET_MAX_UNLOCK state with the SET MAX FREEZE
LOCK command, then the device returns command aborted.
The READ NATIVE MAX ADDRESS command is not executed just before this
command. The command is the SET MAX ADDRESS command if it is the
command just after the READ NATIVE MAX ADDRESS command is executed.
