9.12.2 Target
When a remote NFC initiator has activated the local NFC target handled in the PN544,
the host receives the proprietary event “NXP_EVT_NFC_ACTIVATED”. Then the host
can exchange data with the remote peer receiving event “NXP_EVT_NFC_RCV_DATA”
and using event “NXP_EVT_NFC_SND_DATA”. When the remote NFC initiator closes
the communication, the host receives event “NXP_EVT_NFC_DEACTIVATED”.

Note:
In case of NFC target active mode, the clock may be requested (according to
PlClockRequest configuration) as PN544 shall generate its own field.
