4-3 Commands and Responses during CR Control
3) Write identical data
Use this command to write identical data to tags by the page. Data is written to user-specified pages.
This command is useful when writing the same data to multiple pages (specification is required only
once).
There is no need to perform the verify read process, since this command performs it as part of its
execution.
Command
As parameters, the command sends specification of the pages to be written and the data to write to the
specified pages one page at a time. The page specification is as follows: The bits that correspond to the
pages to be written are set to 1, and all other bits are set to 0. This binary number is converted to
hexadecimal and sent with the command. Specify the write data sequentially in ascending order of the
pages specified. In the case of a Tag equipped with I-CODE1, specify the write data in the order:
F⇒0⇒1⇒···⇒A.
