Lock Function

b7 b6 b5
The Lock function protects against data being erased due to the unintentional
overwriting of fixed data stored in the Tags.
There is a lock setting area in the Tag's system area, so you can write-
protect user-defined areas by page. If a write command is performed on a
page that is write-protected, a write processing error will occur.
The lock setting area is configured using one bit per page, to a total of 12 bits
of data. Make the lock settings using the Lock Command (LK).
Refer to 5-3-6 System Commands and Responses for details.

Note: With the Lock function used in the V720 Series, you cannot turn OFF the lock
settings. Data cannot be written twice to pages that are write-protected, so
be careful when using the function.
