Functional Specification
3.2.5 WRITE ACCESS CONDITIONS
The Write Access Condition bits in block -1 determine the write access conditions for each of the 28 user
blocks and the special data block. These bits can be set only to 1 with a lock command (and never be
changed back to 0), i.e. already write protected blocks can never be written to from this moment on.
In block –2 each byte can be individually locked.
Changing of the Write Access conditions must be done in secure environment. The label must not be
moved out of the communication field of the antenna during writing! We recommend to put the label
close to the antenna and not to remove it during operation.
