18.3.1.7 Receive Command
18.3.1.8 Transceive Command
18.3.1.9 MFAuthent Command
The MFRC522activates the receiver path and waits for any data stream to be received.
The correct settings have to be chosen before starting this command.
This command terminates automatically when the received data stream ends. This is
indicated either by the end of frame pattern or by the length byte depending on the
selected framing and speed.
Remark: If the bit RxMultiple in the RxModeReg register is set to logic 1, the Receive
This circular command repeats transmitting data from the FIFO and receiving data from
the RF field continuously. The first action is transmitting and after a transmission the
command is changed to receive a data stream.
Each transmission process has to be started by setting bit StartSend in the register
BitFramingReg to logic 1. This command has to be cleared by software by writing any
command to register CommandReg e.g. the command idle.
Remark: If the bit RxMultiple in register RxModeReg is set to logic 1, this command will

Remark: When the MFAuthent command is active, any FIFO access is blocked. Anyhow
