COMPANY PUBLIC

19.3.1.7 Receive
19.3.1.8 Transceive
19.3.1.9 MFAuthent
The CRC preset value is controlled by the ModeReg register’s CRCPreset[1:0] bits. The
value is loaded in to the CRC coprocessor when the command starts.
This command must be terminated by writing a command to the CommandReg register,
such as, the Idle command.
If the AutoTestReg register’s SelfTest[3:0] bits are set correctly, the PN512 enters Self
Test mode. Starting the CalcCRC command initiates a digital self test. The result of the
self test is written to the FIFO buffer.
The FIFO buffer content is immediately transmitted after starting this command. Before
transmitting the FIFO buffer content, all relevant registers must be set for data
transmission.
This command automatically terminates when the FIFO buffer is empty. It can be
terminated by another command written to the CommandReg register.
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 PN512 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 will 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 Mini, MIFARE 1K and MIFARE 4K card. The following data is written to the
FIFO buffer before the command can be activated:
