The PN512 behavior is determined by a state machine capable to perform a certain set of
commands. By writing the according command to the Command-Register the command is
executed.
Arguments and/or data necessary to process a command are exchanged via the
FIFO-buffer.

Each command, that needs a data stream (or data byte stream) as input will
immediately process the data it finds in the FIFO-buffer. An exception to this rule is
the Transceive command. Using this command the transmission is started with the
StartSend bit in the BitFramingReg register.
Each command that needs a certain number of arguments will start processing only
when it has received the correct number of arguments via the FIFO-buffer.
The FIFO-buffer is not cleared automatically at command start. Therefore, it is also
possible to write the command arguments and/or the data bytes into the FIFO-buffer
and start the command afterwards.
Each command may be interrupted by the host controller by writing a new command
code into the Command-Register e.g.: the Idle-Command.
No action; cancels current command execution.
Configures the PN512 for FeliCa, MIFARE and NFCIP-1 communication
Generates a 10 byte random ID number
Activates the CRC co-processor or performs a selftest.
Transmits data from the FIFO-buffer.
No command change. This command can be used to modify different bits in the
command register without touching the command. E.G. Power down bit.
Activates the receiver circuitry.
If bit Initiator in the register ControlReg is set to 1:
Transmits data from FIFO-buffer and automatically activates the receiver after
transmission is finished.
If bit Initiator in the register ControlReg is set to 0:
Receives data and automatically activates the transmitter after reception.
Handles FeliCa polling (Card Operation mode only) and MIFARE anticollision
(Card Operation mode only)
Performs the MIFARE authentication in MIFARE Reader/Writer mode only
Resets the PN512
