8.4.1 Active communication mode
Active communication mode means both the initiator and the target are using their own
RF field to transmit data.
Table 9.
The contactless UART of PN512 and a dedicated host controller are required to handle
the NFCIP-1 protocol.
Note: Transfer Speeds above 424 kbit/s are not defined in the NFCIP-1 standard. The
PN512 supports these transfer speeds only with dedicated external circuits.
