8.2.3 NFCIP-1 framing and coding

The NFCIP-1 framing and coding in Active and Passive Communication mode is defined

in the NFCIP-1 standard.

8.2.4 NFCIP-1 Protocol Support

The NFCIP-1 protocol is not completely described in this document. For detailed

explanation of the protocol refer to the NFCIP-1 standard. However the datalink layer is

according to the following policy:

• Speed shall not be changed while continuum data exchange in a transaction.

• Transaction includes initialization and anticollision methods and data exchange (in

continuous way, meaning no interruption by another transaction).

In order not to disturb current infrastructure based on 13.56 MHz general rules to start

NFCIP-1 communication are defined in the following way.

1. Per default NFCIP-1 device is in Target mode meaning its RF field is switched off.

2. The RF level detector is active.

3. Only if application requires the NFCIP-1 device shall switch to Initiator mode.

4. Initiator shall only switch on its RF field if no external RF field is detected by RF Level

detector during a time of TIDT.

5. The initiator performs initialization according to the selected mode.

8.3 Card Operation mode

The PN511 can be addressed like a FeliCa or ISO 14443A/Mifare card. This means that

the PN511 can generate an answer in a load modulation scheme according to the

ISO 14443A/Mifare or FeliCa interface description.

Note: The PN511 does not support a complete card protocol. This has to be handled by a

dedicated card SAM or a host controller. The card-SAM is optional.
