Hello,
I am considering using CLRC663 for reader/writer applications and wanted to know how the SAM module can be used to protect NFC communication. Namely I wanted to know the following:
1) How are encryption keys distributed? Is a license required for this? If so, where can I find more information about this?
2) How are these secret keys loaded into SAM?
3) Does SAM require its own I2C interface (separate from the host I2C/control interface)
4) Can SAM secret keys be read via its I2C interface? If so, how can this be protected? Is there a data direction flow control?
Thank you!
