PRODUCTION DATA.
Table 6-30 describes the ISO/IEC 14443 High-Bit-Rate and Parity Options register.
Function: Selects the ISO subsets for ISO/IEC 14443 – TX | |||
Default: 0x00 at POR = H or EN = L, and at each write to ISO Control register | |||
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 | ||
B1 | Unused | ||
B0 | Unused |
