What is the default value of user memory and where is this stated in the datasheet for the ST25DV NFC EEPROM chip?

I would like to start setting area protection passwords on some of these chips. I have a FEIG RFID reader which I can do this through using the ST25PC-NFC Windows Application, but the reader won't fit into the space I need to reach the chip during n...

We are using Area 1 for a 32 byte header, and Area 2 is being used as general EEPROM storage (ENDA1 = 0x00, ENDA2=ENDA3=ENDA4=0x0F). When I setup the system ENDAx registers like this and I try to do a read across the Area1-Area2 boundary the first ...
