RFU (Set to 0000b.)
Set to the same value as that for the
protocol type (4 bits) of the ATQB
parameter's second byte.
RFU (Set to 0000b.)
0000b: RFID does not support CID.
See CRC_B ISO/IEC14443-3.
PCD→RFID, the RFID will
generate no response.
If parameters other than those
on the left are set, the RFID
will generate no response.
The RFID operates with:
x bits 7-4 ignored
x no response generated
except when bits 3-0 are set
to 0000b
