8.1.3.5 64 bit password protection

Command Code = BBh

With the 64-bit Password Protection command the Label IC can be instructed that both of

the Read and Write passwords are required to get access to password protected blocks

(pages). This mode can be enabled if the Read and Write passwords have already been

transmitted with a Set Password command before.

If the 64-bit password protection is enabled both passwords are required for read & write

access to protected blocks (pages).
