Remarks Class 1 tags are used to store EPC data. EPC data is stored in the @ID
segment, bytes 0-7 for 64 bit and bytes 1-11 for 96-bit tags. The values for
the parameters and for the TAGFIELD command do not
need to be entered when writing EPC data, as these are assigned automatically.
The Kill passcode can be adressed as byte 12 in EPC-96 (byte 8
in EPC-64). It must however be adressed independently with a
TAGFIELD,"@ID",12,1 command.
The Class 1 standard defines a a tag CRC (cyclyc redundancy check) for
tag ID bits, and if incorrect, the tag will not be detected by a TAGREAD
operation.
Erasing all tag information is done by the following comand:
TAGFIELD "@ID",0,0
TAGFORMAT "HEX"
TAGWRITE ""
