National bodies that are members of ISO or IEC participate in the devel

7、opment of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmen

8、tal, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of th

9、e joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. A

10、ttention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 16353 was prepared by Ecma International (as ECMA-390) and was adopted, under a specia

11、l “fast- track procedure”, by Joint Technical Committee ISO/IEC JTC 1, Information technology, in parallel with its approval by national bodies of ISO and IEC.

12、al Standard defines commands, responses and their transmission, allowing the exchange of control and state information between the transceiver and the front-end as specified in ISO/IEC 28361. Such exchange may include indication of the presence of the RF field and control information to change data

NFC-FEC shall move from Escape to Command Ready after receiving RES_ACK or after expiry of the time

20、out specified in 8.4. 7.2 Command Ready state NFC-FEC allows transmission of commands in the Command Ready state. After submission of a command, NFC-FEC shall move to Command Busy state. CMD_QUIT or expiry of the timeout specified in 8.4 shall move NFC-FEC to the Quit state. 7.3 Command Busy state W

21、hen a response is transmitted, or after expiry of the timeout specified in 8.4, NFC-FEC shall move back to Command Ready state. 7.4 Quit state Reception of RES_ACK or after expiry of the timeout specified in 8.4, NFC-FEC shall move to ON.

31、f communication” symbol specified in 9.1 and 9.2 respectively. The odd parity bit P shall be set such that the number of ONEs is odd in (bit 1 to bit 8, P). 9.1 Transceiver Frames The transceiver shall use Manchester encoding as defined in ISO/IEC 28361:2007, 8.1 and the bit coding for f CLK /128 as

32、 defined in ISO/IEC 28361:2007, 8.3.2. Transceiver frames shall use the following framing. Start of communication: ONE. n *(8 data bits (ZERO or ONE) + odd parity bit with n=1). The LSB of each byte is transmitted first. End of communication: HIGH for one bit duration. 9.2 Front-end Frames The RF fr

33、ont-end shall use Modified Miller encoding as defined in ISO/IEC 28361:2007, 8.2 and the bit coding for a bit rate of f CLK /128 as defined in ISO/IEC 28361:2007, 8.3.1. Front-end frames shall use the following framing. Start of communication: ZERO. n *(8 data bits (ZERO or ONE) + odd parity bit with n=1). The LSB of each byte is transmitted first. End of communication: ZERO followed by no gating for two bit durations. ISO/IEC 16353:2011(E) ICS 35.100.10 Price based on 4 pages ISO/IEC 2011 All rights reserved
