PRODUCTION DATA.
Table 6-20 describes the bit fields of the ISO14443A High-Bit-Rate and Parity Options register. This register l the ISO subsets for ISO/IEC 14443 A transmit.
Default Value: 0x00, set at POR = H or EN = L and at each write to ISO Control register
BIT NO. | BIT NAME | FUNCTION | DESCRIPTION |
---|---|---|---|
B7 | dif_tx_br | TX bit rate different from RX bit rate enable | Valid for ISO/IEC 14443 A or B high bit rate |
B6 | tx_br1 | TX bit rate | tx_br1 = 0, tx_br = 0: 106 kbps tx_br1 = 0, tx_br = 1: 212 kbps tx_br1 = 1, tx_br = 0: 424 kbps tx_br1 = 1, tx_br = 1: 848 kbps |
B5 | tx_br0 | ||
B4 | parity-2tx | 1 = Parity odd except last byte, which is even for TX | For ISO/IEC 14443 A high-bit-rate coding and decoding |
B3 | parity-2rx | 1 = Parity odd except last byte, which is even for RX | |
B2 | Unused | ||
