Contactless reader IC
Selects internal receiver settings.
Selects minimum threshold level for the bit decoder.
If set to 1, the EGT is checked and if it is too long
a protocol error is set. (This is only valid for ISO/IEC14443 Type B)
Enables the EMD suppression according ISO/IEC14443. If an error
occurs within the first three bytes, these three bytes are assumed to be
EMD, ignored and the FIFO is reset. A collision is treated as an error
as well If a valid SOF was received, the EMD_Sup is set and a frame
of less than 3 bytes had been received. RX_IRq is not set in this EMD
error cases. If RxForceCRCWrite is set, the FIFO should not be read
out before three bytes are written into.
2 to 0
Defines the baud rate of the receiving signal.
2h: 26 kBd
3h: 52 kBd
4h: 106 kBd
5h: 212 kBd
6h: 424 kBd
7h: 847 kBd
all remaining values are RFU
Table 156. RxCtrl bits
Table 157. RxWait register (address 36h)
Table 158. RxWait bits
If set to 0, the RxWait time is RxWait
If set to 1, the RxWait time is RxWait
6 to 0
Defines the time after sending, where every input is ignored.
