Remark: The MFRC522 has an extra supply pin (SVDD and PVSS as Ground line) for the
The following parameters of the CRC co-processor can be configured. The CRC preset
value can either be 0000h, 6363h, A671h or FFFFh depending on the bits CRCPreset in
register ModeReg.
The CRC polynomial for the 16-bit CRC is fixed to x
The register CRCResultReg indicates the result of the CRC calculation. This register is
split into two 8-bit registers indicating the higher and lower byte.
The bit MSBFirst in the register ModeReg indicates that data will be loaded with MSB first.
