10.3.1.6 NoCmdChange command
10.3.1.7 Receive command
10.3.1.8 Transceive command
10.3.1.9 MFAuthent command
This command does not influence any running command in the CommandReg register. It
can be used to manipulate any bit except the CommandReg register Command[3:0] bits,
for example, the RcvOff bit or the PowerDown bit.
The MFRC523 activates the receiver path and waits for a data stream to be received. The
correct settings must be chosen before starting this command.
This command automatically terminates when the data stream ends. This is indicated
either by the end of frame pattern or by the length byte depending on the selected frame
type and speed.
Remark: If the RxModeReg register’s RxMultiple bit is set to logic 1, the Receive
command does not automatically terminate. It must be terminated by starting another
command in the CommandReg register.
This command continuously repeats the transmission of data from the FIFO buffer and the
reception of data from the RF field. The first action is transmit and after transmission the
command is changed to receive a data stream.
Each transmit process must be started by setting the BitFramingReg register’s StartSend
bit to logic 1. This command must be cleared by writing any command to the
CommandReg register.
Remark: If the RxModeReg register’s RxMultiple bit is set to logic 1, the Transceive
command never leaves the receive state because this state cannot be cancelled
automatically.
This command manages MIFARE authentication to enable a secure communication to
any MIFARE card. The following data is written to the FIFO buffer before the command
can be activated:
12 bytes in total are written to the FIFO.
