The LOCK PAGE PROTECTION CONDITION command locks the protection pointer
address and the status of the page protection conditions if the Read and Write
passwords have been transmitted first with the SET PASSWORD command.
The timing of the command is write alike.

Remark: If the transmitted protection pointer address does not match with the stored
address the label will respond according to the error handling (see Section 9.6 "Error
handling").

9.5.3.8 DESTROY
Command code = B9h
The DESTROY SLIX2 command enables the ICODE SLIX2 Label IC to be destroyed if
the Destroy password is correct. This command is irreversible and the ICODE SLIX2 will
never respond to any command again.
The DESTROY SLIX2 command can only be executed in addressed or selected mode.
The XOR password has to be calculated with the password and two times the received
random number from the last GET RANDOM NUMBER command:
XOR_Password[31:0] = Password[31:0] XOR {Random_Number[15:0],
Random_Number[15:0]}.
The timing of the command is write alike.
