The internal CRC coprocessor calculates the CRC value based on ISO/IEC 14443 A
part 3 and handles parity generation internally based on the transfer speed. Automatic
parity generation can be switched off using the ManualRCVReg register’s ParityDisable
bit.
The MFRC523 reader IC fully supports the ISO 14443 international standard which
includes the communication schemes ISO 14443 A and ISO 14443 B. Refer to the
ISO 14443 reference documents Identification cards - Contactless integrated circuit cards
- Proximity cards (parts 1 to 4).
Remark: NXP Semiconductors does not offer a software library to enable design-in of the
ISO 14443 B protocol.
The MFRC523 supports direct interfacing to hosts using SPI, I
interfaces. The MFRC523 resets its interface and checks the current host interface type
automatically after performing a power-on or hard reset.
The MFRC523 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.
