Otherwise, apply the procedure of Section 12.3.3 to the EPC Tag URI from Step 1 toobtain a Pure Identity EPC URI. This is the final result.15.2.4 Decoding of Control InformationThis procedure is used as a subroutine by the decoding procedures in Sections 15.2.1and 15.2.2. It calculates a string that is inserted immediately following theurn:epc:tag: or urn:epc:raw: prefix, containing the values of all non-zerocontrol information fields (apart from the filter value). If all such fields are zero, thisprocedure returns an empty string, in which case nothing additional is inserted after theurn:epc:tag: or urn:epc:raw: prefix.Given: The contents of the EPC Memory Bank of a Gen 2 tagProcedure:1. If bit 17 h is zero, extract bits 18 h – 1F h and consider them to be an unsigned integer A.If A is non-zero, append the string [att=xAA] (square brackets included) to CF,where AA is the value of A as a two-digit hexadecimal numeral.2. If bit 15 h is non-zero, append the string [umi=1] (square brackets included) to CF.3. If bit 16 h is non-zero, extract bits 210 h – 21F h and consider them to be an unsignedinteger X. If X is non-zero, append the string [xpc=xXXXX] (square bracketsincluded) to CF, where XXXX is the value of X as a four-digit hexadecimal numeral.Note that in the Gen 2 air interface, bits 210 h – 21F h are inserted into thebackscattered inventory data immediately following bit 1F h , when bit 16 h is non-zero.See [UHFC1G2].4. Return the resulting string (which may be empty).16 Tag Identification (TID) Memory Bank ContentsTo conform to this specification, the Tag Identification memory bank (bank 10) SHALLcontain an 8 bit ISO/IEC 15963 allocation class identifier of E2 h at memory locations 00 hto 07 h . TID memory locations 08 h to 13 h SHALL contain a 12 bit Tag mask designeridentifier (MDID) obtainable from EPCglobal. TID memory locations 14 h to 1F h SHALLcontain a 12-bit vendor-defined Tag model number (TMN) as described below.EPCglobal will assign two MDIDs to each mask designer, one with bit 08 h equal to oneand one with bit 08 h equal to zero. Readers and applications that are not configured tohandle the extended TID will treat both of these numbers as a 12 bit MDID. Readers andapplications that are configured to handle the extended TID will recognize the TIDmemory location 08 h as the Extended Tag Identification bit. The value of this bitindicates the format of the rest of the TID. A value of zero indicates a short TID in whichthe values beyond address 1F h are not defined. A value of one indicates an Extended TagIdentification (XTID) in which the memory locations beyond 1F h contain additional dataas specified in Section 16.2.The Tag model number (TMN) may be assigned any value by the holder of a givenMDID. However, [UHFC1G2] states “TID memory locations above 07 h shall be definedCopyright ©2005- 2011 GS1 AISBL, All Rights Reserved. Page 116 of 218
