Application Data (APP)
APP is an additional 32 bits of information transmitted as part of the ATQB response. This field is defined by the
customer during personalization. The fourth byte is programmed by Atmel at the factory with a memory density code
(see Table 107); this byte can be redefined by the card manufacturer if desired. APP may be set to any value.
Table 107.
Receive Buffer Max Code (RBmax)
This 8-bit register is transmitted as Protocol 2 byte of the ATQB response. This register is programmed by Atmel with
the receive buffer maximum frame size code. This field can be reprogrammed by the customer during personalization if
desired. The value of this protocol byte is restricted by ISO/IEC 14443 Part 3 to the values $00, $10, $20, $30, $40,
$50, $60, $70, or $80 only. Use of an unapproved value in this register is likely to cause PCDs to malfunction.
The Protocol 2 byte of the ATQB response is defined in ISO/IEC 14443 Part 3, section 7.9 . This byte contains the Part
4 compliance code in the lower 4 bits and the code for the maximum frame size supported by the card in the upper 4
bits. CryptoRF must return a value of $0 in the Part 4 compliance bits to indicate the PICC does not support the
optional ISO/IEC 14443 Part 4 Active State protocol. The coding of the card maximum frame size bits is shown in
Table 108.
Table 108.
The PCD will store the lower 4 bits of ATQB protocol byte 2 in a register and echo it back to a selected PICC in the
lower 4 bits of ATTRIB parameter byte 3. CryptoRF will not accept an ATTRIB command with a non-zero value in
parameter byte 3. Note that intelligent PCDs will reject invalid ATQB responses and will not send invalid ATTRIB
commands.
