Product data sheet Rev. 3.3 — 3 July 2020 COMPANY PUBLIC 544533 66 / 133 • FAST INVENTORY READ in extended mode (see Section 8.2.3.5.2) • AUTHENTICATE to move to SELECTED SECURE state (see Section 8.2.3.4.4) 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.
