The RF level detector detects the presence of an external RF-field delivered by the antenna to the RX pin. The data mode detector detects a ISO/IEC 14443-A MIFARE, FeliCa or NFCIP-1 mode in order to prepare the internal receiver to demodulate signals, which are sent to the PN532. The NFC-WI/S2C interface supports communication to secure IC. It also supports digital signals for transfer speeds above 424 kbit/s. The CL UART handles the protocol requirements for the communication schemes in co-operation with the appropriate firmware. The FIFO buffer allows a convenient data transfer from the 80C51 to the CIU and vice versa. Fig 2.

Table 4 describes the physical parameters. With appropriate firmware, the PN532 can handle the FeliCa protocol. The FeliCa Framing and coding must comply with the following table: To enable the FeliCa communication a 6-byte preamble (00h, 00h, 00h, 00h, 00h, 00h) and 2-byte SYNC bytes (B2h, 4Dh) are sent to synchronize the receiver. The following LEN byte indicates the length of the sent data bytes plus the LEN byte itself. The CRC calculation is done according to the FeliCa definitions with the MSB first. To transmit data on the RF interface, the 80C51 has to send the LEN and data bytes to the CIU. The Preamble and SYNC bytes are generated by the CIU automatically and must not be written to the FIFO. The CIU performs internally the CRC calculation and adds the result to the frame. The starting value for the CRC Polynomial is 2 null bytes: (00h), (00h) Example of frame: Fig 5.
