9.1.4.2 SPI write data
Table 8.
[1]
The structure shown in
up to n-data bytes. The first byte sent defines both the mode and the address.
Table 9.
The address byte must meet the following criteria:
SPI write mode writes all data to the address defined in byte 0 enabling effective write
cycles to the FIFO buffer.
Table 10.

Remark: The data bus pins D7 to D1 must be disconnected.

All reserved bits must be set to logic 0.
the MSB of the first byte sets the mode. To write data to the MFRC531, the MSB is set
to logic 0
bits [6:1] define the address
the LSB should be set to logic 0.
All reserved bits must be set to logic 0.
