8.2.3.2 Configuration operations

8.2.3.2.1 READ CONFIGURATION

Command code = C0h

The READ CONFIG command returns configuration memory content starting with the

first block defined by the Block Address and reads Number of Blocks + 1 configuration

blocks.

Access to the configuration blocks depends on the status and definition of the related

block within the configuration memory (see Section 8.1.3).

If one of the requested configuration blocks is not accessible due to the actual status,

NTAG 5 link will respond with Error_flag set.

A READ CONFIG command can read one or multiple blocks of the following areas of the

configuration memory within one command execution:

• Block 00h to block 17h

• Keys can only be read separately if "NOT active" or after a mutual authentication with a

key with the Crypto Config privilege set in "active" state

Key0: block 20h-23h

Key1: block 24h-27h

Key2: block 28h-2Bh

Key3: block 2Ch-2Fh

• rest of configuration memory

Only Option_flag = 0b is supported.
