Communications Command

Caution
From Page FD to Page FE is a system area for write-protect and
QUIET/EAS settings. Depending on the content of write data, a Tag may
become write-protected or inaccessible, so be sure to understand these
pages fully before use.
It is strongly recommended that you use a system command to write in
these pages (refer to 5-4) rather than using the write command.
