8.3.7.2 ISO/IEC 18092 framing and coding
The ISO/IEC 18092 framing and coding in Passive communication mode is defined in the
ISO/IEC 18092 standard.

8.3.7.3 ISO/IEC 18092 protocol support
The ISO/IEC 18092 protocol is not described in this document. For a detailed explanation
of the protocol, refer to the ISO/IEC 18092 standard.
8.3.8 EPC Class-1 HF and ICODE
8.3.8.1 Data encoding ICODE
The ICODE protocols have mainly three different methods of data encoding:
• “1” out of “4” coding scheme
• “1” out of “256” coding scheme
• “Return to Zero” (RZ) coding scheme.
Data encoding for all three coding schemes is done by the ICODE generator.
The supported EPC Class-1 HF modes are:
• 2 pulse for 424 Kbit subcarrier
• 4 pulse for 424 Kbit subcarrier
• 2 pulse for 848 Kbit subcarrier
• 4 pulse for 848 Kbit subcarrier
8.4 Host interfaces
8.4.1 Host interface configuration
The CLRC663 supports direct interfacing of various hosts as the SPI, I²C, I²CL and serial
UART interface type. The CLRC663 resets its interface and checks the current host
interface type automatically having performed a power-up or resuming from power down.
The CLRC663 identifies the host interface by the means of the logic levels on the control
pins after the Cold Reset Phase. This is done by a combination of fixed pin
connections.The following table shows the possible configurations defined by
IFSEL1,IFSEL0:
