Remark: The data byte can be sent directly after the address byte on pin RX.
Address byte: The address byte has to meet the following format:
The MSB of the first byte sets the mode used. To read data from the MFRC522, the MSB is set to logic 1. To write data to the
MFRC522 the MSB is set to logic 0. Bit 6 is reserved for future use, and bits 5 to 0 define the address; see
