6.14.1.1.2 ISO Control Register (0x01)
Table 6-17 describes the bit fields of the ISO Control register. This register controls the selection of ISO
standard protocol, direct mode, and receive CRC.
Default Value: 0x02 , reset at EN = L or POR = H
Table 6-17. ISO Control Register (0x01)
BIT NO. BIT NAME FUNCTION DESCRIPTION
B7 rx_crc_n CRC receive selection
1 = No RX CRC (CRC not present in the response)
0 = RX CRC (CRC is present in the response)
B6 dir_mode
Direct mode type
selection 0 = Direct mode 0
1 = Direct mode 1
B5 rfid RFID mode
0 = RFID mode
1 = Reserved (should be set to 0)
B4 iso_4 RFID
See Table 6-18 for B0:B4 settings based on the ISO protocol that the
application requires.
B3 iso_3 RFID
B2 iso_2 RFID
B1 iso_1 RFID
B0 iso_0 RFID
(1) For ISO/IEC 14443 A or B, when bit rate of TX is different from RX, settings can be made in register 0x02 or 0x03.
