9.1.4.1 SPI read data
Table 6.
Figure 6
Remark: The SPI implementation for MFRC531 conforms to the SPI standard and
ensures that the MFRC531 can only be addressed as a slave.
The structure shown in
up to n-data bytes. The first byte sent defines both, the mode and the address.

the Most Significant Bit (MSB) of the first byte sets the mode. To read data from the
MFRC531 the MSB is set to logic 1
bits [6:1] define the address
the Least Significant Bit (LSB) should be set to logic 0.
