GEN2
For Gen2, if Option=00, the write tag data is performed without the select option with the
following format:
In the previous example, the reader can singulate a tag with Q=0 and would try to write N
bytes of data into the first tag it can see, starting at the address 0x2 of EPC MemBank
(the first word of the tag’s EPC).
If Option=01, the write tag data is performed with the select option that enables you to
choose a tag from a population of tags based on its Tag ID with the following format:
In this example, if N=4, the reader issues a Select command to singulate the desired tag
and then would write 4 bytes of data into the tag memory of a 96-bit tag with the specified
Tag ID, starting at the address 0x2 of the Reserved MemBank (the first word of the Kill
Password of the tag).
Note
In both examples, N is a variable value that is an even, nonzero number less
than 32.
The 32-bit Address field is the offset from the MemBank origin, in 16-bit words, where the
contents of the Data field is written. It corresponds to the
WordPtr argument in the Gen2
command specification.
The 8-bit MemBank field specifies which of the tag’s memory banks is to be addressed. It
corresponds to the
Gen2 argument of the same name. Its values are as follows.
