10. MFRC523 command set
The MFRC523 operation is determined by a state machine capable of performing a set of
commands. A command is executed by writing a command code (see
Table 150
) to the
CommandReg register.
Arguments and data necessary to process a command are exchanged using the FIFO
buffer.
10.1 General description
The MFRC523 operation is determined by a state machine capable of performing a set of
commands. A command is executed by writing a command code (see
Table 150
) to the
CommandReg register.
Arguments and/or data necessary to process a command are exchanged via the FIFO
buffer.
10.2 General behavior
Each command that needs a data bit stream (or data byte stream) as an input
immediately processes any data in the FIFO buffer. An exception to this rule is the
Transceive command. Using this command, transmission is started with the
BitFramingReg register’s StartSend bit.
Each command that needs a certain number of arguments, starts processing only
when it has received the correct number of arguments from the FIFO buffer.
The FIFO buffer is not automatically cleared when commands start. This makes it
possible to write command arguments and/or the data bytes to the FIFO buffer and
then start the command.
Each command can be interrupted by the host writing a new command code to the
CommandReg register, for example, the Idle command.

no action, cancels current command execution
stores 25 bytes into the internal buffer
generates a 10-byte random ID number
activates the CRC coprocessor or performs a self-test
transmits data from the FIFO buffer
no command change, can be used to modify the
CommandReg register bits without affecting the command,
for example, the PowerDown bit
activates the receiver circuits
transmits data from FIFO buffer to antenna and automatically
activates the receiver after transmission
