Present-sector password:
The Present-sector password command is used to present one of the three passwords
to the M24LR16E-R in order to modify the access rights of all the memory sectors
linked to that password
password is correct, the access rights remain activated until the tag is powered off or
until a new Present-sector password command is issued. If the presented password
value is not correct, all the access rights of all the memory sectors are deactivated.
