8.3.2.2 SPI write data
8.3.2.3 SPI Read and Write address byte
The first byte sent defines both the mode and the address.
Table 6.
[1]
Remark: The MSB must be sent first.
To write data to the MFRC523 using SPI requires the byte order shown in
possible to write up to n-data bytes by only sending one address byte.
The first send byte defines both the mode and the address byte.
Table 7.
[1]
Remark: The MSB must be sent first.
The read address byte must meet the following criteria:
