Description
enables the CRC calculation during reception
Remark: can only be set to logic 0 at 106 kBd
defines the bit rate while receiving data
the MFRC522 handles transfer speeds up to 848 kBd
an invalid received data stream (less than 4 bits received) will
be ignored and the receiver remains active
