8.1.3.1 Originality Signature

The Originality signature (see Section 8.8) is stored in first 8 blocks (block 00h to

block 07h) of configuration memory and may be verified by the NFC device using the

corresponding ECC public key. As the NXP originality signature is on default not locked,

it may be re-programmed by the customer. If the originality check is not needed, it may

even be used as additional 32 byte user EEPROM.

8.1.3.2 Configuration Header

The Configuration Header (CH) byte defines the access conditions of both, Customer ID

and Originality Signature.

Configuration Header byte can be read with READ CONFIG command (see

Section 8.2.3.2.1) and written with WRITE CONFIG command (see Section 8.2.3.2.2).

Once locked (set to E7h), CH byte cannot be updated anymore and Originality Signature

and Customer ID gets locked permanently from NFC perspective.

From I2C perspective this block can be read and written if not locked by the I2C section

lock. Once locked, CH byte cannot be updated anymore and Originality Signature and

CID gets locked permanently from I2C perspective.
