Product data sheet
18.3.1.4 CalcCRC command
18.3.1.5 Transmit command
18.3.1.6 NoCmdChange command
18.3.1.7 Receive command
The content of the FIFO is transferred to the CRC co-processor and a CRC calculation is
started. The result of this calculation is stored in the CRCResultReg register. The CRC
calculation is not limited to a dedicated number of bytes. The calculation is not stopped,
when the FIFO gets empty during the data stream. The next byte written to the FIFO is
added to the calculation.
The pre-set value of the CRC is controlled by the CRCPreset bits of the ModeReg register
and the chosen value is loaded to the CRC co-processor when the command is started.
This command has to be terminated by writing any command to the Command-register
e.g. the command Idle.
If the SelfTest bits in the register AutoTestReg are set correct, the PN512 is in Self Test
mode and starting the CalcCRC command performs a digital selftest. The result of the
selftest is written to the FIFO.
The content of the FIFO is transmitted immediately after starting the command. Before
transmitting the FIFO content all relevant register have to be set to transmit data in the
selected mode.
This command terminates automatically when the FIFO gets empty. It can be terminated
by any other command written to the command register.
This command does not influence any ongoing command in the CommandReg register. It
can be used to manipulate any bit except the command bits in the CommandReg register,
e.g. the bits RcvOff or Power-down.
The PN512 activates the receiver path and waits for any data stream to be received. The
correct settings for the expected mode 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.
Note: If the bit RxMultiple in the RxModeReg register is set to logic 1 the Receive
command does not terminate automatically. It has to be terminated by activating any other
command in the CommandReg register.
