PRODUCTION DATA.
Table 6-19 describes the bit fields of the ISO14443B TX Options register. This register selects the ISO subsets for ISO/IEC 14443 B transmit.
Default Value: 0x00, set at POR = H or EN = L
BIT NO. | BIT NAME | FUNCTION | DESCRIPTION |
---|---|---|---|
B7 | egt2 | TX EGT time select. B7 is the MSB. | This 3-bit code defines the number of etu (0 to 7) that separate two characters. ISO/IEC 14443 B TX only. |
B6 | egt1 | ||
B5 | egt0 | ||
B4 | eof_l0 | 1 = EOF → 0 length 11 etu 0 = EOF → 0 length 10 etu |
ISO/IEC 14443 B TX only |
B3 | sof_l1 | 1 = SOF → 1 length 03 etu 0 = SOF → 1 length 02 etu |
|
B2 | sof_l0 | 1 = SOF → 0 length 11 etu 0 = SOF → 0 length 10 etu |
|
B1 | l_egt | 1 = EGT after each byte 0 = EGT after last byte is omitted |
|
B0 | Unused |
