12.2.5 ISO/IEC18000-3 Mode 3 VCD mode
The ISO/IEC 18000-3 mode 3 is not described in this document. For a detailed
explanation of the protocol, refer to the ISO/IEC 18000-3 standard.

12.3 NFC modes

12.3.1 NFCIP – 1 modes
12.3.1.1 Overview
The NFCIP-1 communication differentiates between an Active and a Passive
Communication 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
• Initiator: generates RF field at 13.56 MHz and starts the NFCIP-1 communication
• Target: responds to initiator command either in a load modulation scheme in Passive
In order to fully support the NFCIP-1 standard, the PN7462 family 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.
12.3.1.2 Active communication mode
Active communication mode means both the initiator and the target are using their own
RF field to transmit data.
