There are several registers that define the polling response of CryptoRF, which are written during the personalization
process. The ISO/IEC 14443 Part 3 requirements must be considered when programming these registers. Incorrect
personalization of these registers may cause readers to reject cards or to become confused and unable to complete
the transaction. This appendix describes the requirements for programming the polling registers for operation with
ISO/IEC 14443 compliant readers and systems.
The RF reader (PCD) searches for Type B cards by issuing REQB or WUPB polling commands. These commands
contain an AFI (Application Family Identifier) code to poll for only cards with a matching AFI code. Applications
supporting multiple cards may also poll using the Slot MARKER command. See Appendix N for a detailed description
of the anticollision procedures.
The answer to any of these polling commands is called the ATQB response. This response contains a card serial
number (PUPI), which is used to identify a specific card during the anticollision process, along with three protocol
bytes. The protocol bytes tell the PCD what communication capabilities and options the card supports, and are used by
the reader to configure itself for optimum communications with the card.
The ATQB response of CryptoRF contains several values that are located in registers in the anticollision section of the
System Zone (see Figure 42 and Figure 43). The values stored in the following registers are used during anticollision:
PUPI, APP, RBmax, AFI.
Figure 42.
Figure 43.
The REQB/WUPB polling command and response are shown in Figure 44 with color-coding which matches Figure 42
and Figure 43. Nine bytes of the ATQB response are customer programmable on CryptoRF. In addition, the AFI code
used for selection of cards for a particular application during anticollision is also customer configured.
