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
