The internal CRC coprocessor calculates the CRC value based on ISO/IEC 14443 A
part 3 and handles parity generation internally according to the transfer speed. Automatic
parity generation can be switched off using the MfRxReg register’s ParityDisable bit.
The MFRC522 supports direct interfacing of hosts using SPI, I
interfaces. The MFRC522 resets its interface and checks the current host interface type
automatically after performing a power-on or hard reset. The MFRC522 identifies the host
interface by sensing the logic levels on the control pins after the reset phase. This is done
using a combination of fixed pin connections.
