All rights reserved. Product data sheet Rev. 3.3 — 3 July 2020 COMPANY PUBLIC 544533 98 / 133 Table 227. PICK RANDOM ID response format when Error_flag is set Flags Error Code CRC16 8 bits 8 bits 16 bits After a successful PICK_RANDOM_ID the NTAG 5 link will respond on an INVENTORY command with a random ID as defined in the table below. Table 228. Random ID MSB LSB 63:56 55:48 47:40 39:32 31:24 23:16 15:0 E0h 04h 00h 00h CID_1 CID_0 16-bit random ID 8.2.4 Data integrity Following mechanisms are implemented in the contactless communication link between reader and NTAG 5 link to ensure very reliable data transmission: • 16-bit CRC per block • Bit count checking • Bit coding to distinguish between logic 1, logic 0, and no information • Channel monitoring (protocol sequence and bit stream analysis) 8.2.5 Error Handling 8.2.5.1 Transmission Errors According to ISO/IEC 15693 NTAG 5 link will not respond if a transmission error (CRC, bit coding, bit count, wrong framing) is detected and will silently wait for the next correct received command. 8.2.5.2 Not supported commands or options If the received command or option is not supported, the behavior depends on the addressing mechanism. • Non-Addressed Mode NTAG 5 link remains silent • Addressed or selected Mode NTAG 5 link responds with error code 0Fh (no information given, or error code not supported). If the Inventory flag or the Protocol Extension flag is set, the IC will not respond if the command or option is not supported. • Parameter out of range – Read alike commands If the sum of the first block number and the number of blocks exceeds the total available number of user blocks, the number of transmitted blocks is less than the requested number of blocks. This means that the last returned block is the highest available user block, followed by the 16-bit CRC and the EOF. – Write alike commands If the address of a block to be written does not exist or a block to be written is locked, the behavior of the IC depends on the addressing mechanism. |
