9.1.3.3 FeliCa™ Reader/Writer Functionality
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 internal contactless UART, the internal µC of PN532 and the external host handle the

Table 6:
To enable the FeliCa™ communication a 6 bytes long preamble and 2 bytes Sync bytes
are sent in order to synchronise the internal receiver. The Len byte is an indicator for the
length of the sent data bytes plus the n-data bytes. The CRC calculation is done according
to the FeliCa™ definitions with the MSB first.
To transmit data on the RF interface, the host has to send the Preamble-, Syn-, Len- and
data- bytes to the PN532. Only the internal CRC calculation is made and added internally
of the PN532
The starting value for the CRC Polynomial is 2 null bytes: (0x00), (0x00)
