9.1.4 NFCIP-1 MODE
The NFCIP-1 communication differentiates between an active and a passive
communication mode.
In order to fully support the NFCIP-1 standard the PN532 supports the active and passive
communication mode at the transfer speeds 106 kbit/s, 212 kbit/s and 424 kbit/s as
defined in the NFCIP-1 standard
Fig 6. NFCIP-1 Mode.

Active Communication Mode means both the initiator and the target are using their
own RF field to transmit data
Passive Communication Mode means that the target answers to an initiator command
in a load modulation scheme. The initiator is active in terms of generating the RF field.
Initiator: generates RF field @ 13.56 MHz and starts the NFCIP
Target: responds to initiator command either in a load modulation scheme for passive
communication mode or using a self generated and self modulated RF field for active
communication mode.
