Product data sheet
Fig 10. Schematic Diagram to Write Data.
Write data:
To write data to the MFRC522 using the UART interface the following structure has to be
used.
The first send byte defines both, the mode itself and the address.
Table 143: Byte Order to Write Data
Remark: The data byte can be send directly after the address byte on RX.
Address byte:
The address byte has to fulfil the following format:
The MSB of the first byte sets the used mode. To read data from the MFRC522 the MSB is
set to logic 1. To write data to the MFRC522 the MSB has to be set to logic 0. The bit 6 is
reserved for further use and the bits 5 to 0 define the address.
