The write protection function protects the data kept in the Data Carrier from
being purged by mistake. We recommend the user to write-protect any impor-
tant data after the user writes them to the Data Carrier. The write protection
method is explained below.
By writing write protection end address data to address 0000 of the Data Car-
rier, the area between address 0001 and the end address that has been des-
ignated will be write-protected. Whether or not to execute write protection is
specified by the leftmost bit of address 0000.
