Appendix D. Error Codes
Error Error Code
No Error 0x00
Time Out, the target has not answered 0x01
A CRC error has been detected by the contactless UART 0x02
A Parity error has been detected by the contactless UART 0x03
During a Mifare anti-collision/select operation, an erroneous Bit Count has been
detected 0x04
Framing error during Mifare operation 0x05
An abnormal bit-collision has been detected during bit wise anti-collision at 106
kbps 0x06
Communication buffer size insufficient 0x07
RF Buffer overflow has been detected by the contactless UART (bit BufferOvfl of
the register CL_ERROR) 0x08
In active communication mode, the RF field has not been switched on in time by the
counterpart (as defined in NFCIP-1 standard) 0x0A
RF Protocol error (cf. reference [4], description of the CL_ERROR register) 0x0B
Temperature error: the internal temperature sensor has detected overheating, and
therefore has automatically switched off the antenna drivers 0x0D
Internal buffer overflow 0x0E
Invalid parameter (range, format, …) 0x10
DEP Protocol: The chip configured in target mode does not support the command
received from the initiator (the command received is not one of the following:
ATR_REQ, WUP_REQ, PSL_REQ, DEP_REQ, DSL_REQ, RLS_REQ
, ref. [1]).
0x12
DEP Protocol / Mifare / ISO/IEC 14443-4: The data format does not match to the
specification. Depending on the RF protocol used, it can be:
• Bad length of RF received frame,
• Incorrect value of PCB or PFB,
• Invalid or unexpected RF received frame,
• NAD or DID incoherence. 0x13
Mifare: Authentication error 0x14
ISO/IEC 14443-3: UID Check byte is wrong 0x23
DEP Protocol: Invalid device state, the system is in a state which does not allow the
operation 0x25
Operation not allowed in this configuration (host controller interface) 0x26
This command is not acceptable due to the current context of the chip (Initiator vs.
Target, unknown target number, Target not in the good state, …) 0x27
The chip configured as target has been released by its initiator 0x29
ISO/IEC 14443-3B only: the ID of the card does not match, meaning that the
expected card has been exchanged with another one. 0x2A
ISO/IEC 14443-3B only: the card previously activated has disappeared. 0x2B
Mismatch between the NFCID3 initiator and the NFCID3 target in DEP 212/424
kbps passive. 0x2C
An over-current event has been detected 0x2D
NAD missing in DEP frame 0x2E
