9.12 NFCIP-1
PN544 offers Peer to Peer functionality based on NFCIP-1 protocol through the two
following proprietary gates:

Gate GID
NFCIP1 Initiator RF gate ‘30’
NFCIP1 Target RF gate ‘31’
Table 113. NFC-IP1 Events
Value Event Description
‘01’
NXP_EVT_NFC_SND_DATA
This event conveys payload from the host to the
CLF. In Initiator mode this leads to a DEP_REQ
(information PFB). In Target mode this leads to a
DEP_RES (information PFB).
‘02’
NXP_EVT_NFC_ACTIVATED
This event is sent to the host to notify that NFCIP-1
protocol has been activated. Meaning that, in
initiator mode it has activated a remote NFC target,
and in target mode it has been activated by a
remote NFC initiator
‘03’
NXP_EVT_NFC_DEACTIVATED
This event is sent by the NFC target to its host to
notify that the connection has been closed.
The NFCIP-1link deactivation might have several
reasons:
- The remote NFC Initiator has explicitly performed
a link deactivation
- The NFCIP-1 link has detected an error and it
was not able to recover the communication on
target side
‘04’
NXP_EVT_NFC_RCV_DATA
This event conveys payload from the CLF to the
host. In Initiator mode this event has been
generated due to a DEP_RES. In Target mode this
event has been generated because of a
DEP_REQ.
