correct (see register ErrReg). The first byte of each packet contains the length byte of

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

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.
