12.3.1.7 NFCIP-1 protocol support
The NFCIP-1 protocol is not completely described in this document. The PN7462 family
does not implement any of the high-level protocol functions. This higher-level protocol
function need to be provided by the host. For detailed explanation of the protocol refer to
the NFCIP-1 standard. However, the data link layer is according to the following policy:
• Speed shall not be changed while continuous data exchange in a transaction.
• Transaction includes initialization, anti-collision methods and data exchange (in
In order not to disturb current infrastructure based on 13.56 MHz, the following general
rules to start a NFCIP-1 communication are defined:
