12.7 Hardware support for FeliCa and NFC polling
1. Timer: The PN512 has a timer, which can be programmed in a way that it generates
2. The receiver can be configured in a way to receive continuously. In this mode it can
3. The internal UART adds one byte to the end of every received packet, before it is
4. The length of one packet is 18 or 20 bytes (+ 1 byte Error-Info). The FIFO has a
1. The host controller has to configure the PN512 with the correct polling response
2. To activate the automatic polling in Target mode, the AutoColl Command has to be
3. The PN512 receives the polling command send out by an initiator and answers with
an interrupt at the end of each timeslot, or if required an interrupt is generated at the
end of the last timeslot.

directly after the last packet has been received. This mode is active by setting the bit
RxMultiple in register RxModeReg to 1 and has to be stopped by software.
transferred into the FIFO-buffer. This byte indicates if the received byte packet is
correct (see register ErrReg). The first byte of each packet contains the length byte of
the packet.
length of 64 bytes. This means three packets can be stored in the FIFO at the same
time. If more than three packets are expected, the host controller has to empty the
FIFO, before the FIFO is filled completely. In case of a FIFO-overflow data is lost (See
bit BufferOvfl in register ErrorReg).
parameters for the polling command.
activated.
the polling response. The timeslot is selected automatically (The timeslot itself is
randomly generated, but in the range 0 to TSN, which is defined by the Polling
command). The PN512 compares the system code, stored in byte 17 and 18 of the
Config Command with the system code received by the polling command of an
initiator. If the system code is equal, the PN512 answers according to the configured
polling response. The system code FF (hex) acts as a wildcard for the system code
bytes, i.e. a target of a system code 1234 (hex) answers to the polling command with
one of the following system codes 1234 (hex), 12FF (hex), FF34 (hex) or FFFF (hex).
If the system code does not match no answer is sent back by the PN512.
If a valid command is received by the PN512, which is not a Polling command, no
answer is sent back and the command AutoColl is stopped. The received packet is
stored in the FIFO.
