Description
If cleared, the TxWait time is starting at the End of the send data
(TX)
If set, the TxWait time is starting at the End of the received data
(RX)
If cleared, the TxWait time is TxWait  16/13.56 MHz
If set, the TxWait time is TxWait  0.5 / DBFreq (DBFreq is the
frequency of the bit stream as defined by TxDataCon)
Bit extension of TxWaitLo. TxWaitCtrl bit 5 is MSB.
Defines stop-bits and EGT (= stop-bit + extra guard time EGT) to
be send
0h: no stop-bit, no EGT
1h: 1 stop-bit, no EGT
2h: 1 stop-bit + 1 EGT
3h: 1 stop-bit + 2 EGT
4h: 1 stop-bit + 3 EGT
5h: 1 stop-bit + 4 EGT
6h: 1 stop-bit + 5 EGT
7h: 1 stop-bit + 6 EGT
Note: This is only valid for ISO/IEC14443 Type B
