ST25DV: PROBLEM WRITING STATIC REGISTER ?

[oziesin]

Hi everyone,

I can communicate with ic via i2c. I can write/read on user memory section but when i try to write static registers, i faced foolish value. For example, firstly i read MB_MODE register and value is default '0' then i write '1' on this register. Finally i read again for being assure, and i faced 0x20. That is suprising. I also try all static register and i faced foolish value all of them. Would be appriciate any help.

Thank you.
