Near field communication (NFC) controller

8.1.2 FeliCa PCD mode

The FeliCa mode is the general reader/writer to card communication scheme according to

the FeliCa specification. The following diagram describes the communication on a

physical level, the communication overview describes the physical parameters.

The contactless UART of PN544 and the on-chip CPU handle the FeliCa protocol.

Nevertheless a dedicated external host has to handle the application layer

communication.
