Function
after data transmission, the activation of the receiver is delayed
for RxWait bit-clock cycles. During this frame guard time any
signal on pin RX is ignored.

CRC calculation is performed using ISO/IEC 14443 A
an 8-bit CRC is calculated
a 16-bit CRC is calculated
the last byte(s) of a received frame are interpreted as CRC bytes. If
the CRC is correct, the CRC bytes are not passed to the FIFO. If
the CRC bytes are incorrect, the CRCErr flag is set.
no CRC is expected
a CRC is calculated over the transmitted data and the CRC bytes
are appended to the data stream
no CRC is transmitted
