TheDSFID is typically eight bits inlength, but may be extendedfurther as specified in[ISO15961]. When the DSFIDspecifies Access Method 2, theformat of the remainder of usermemory is “packed objects” asspecified in Section 17. Thisformat is recommended for usein EPC applications. Thephysical encoding in thepacked objects data format isas a sequence of “packedobjects,” where each packedobject includes one or morename-value pairs whose valuesare compacted together.Table 4.Gen 2 Memory MapBusinessData[ISO15961],[ISO15962],Section 17The following diagram illustrates in greater detail the first few bits of the EPC Bank(Bank 01), and in particular shows the various fields within the Protocol Control bits (bits10 h – 1F h , inclusive).Copyright ©2005- 2011 GS1 AISBL, All Rights Reserved.
