Erase Block Tag Specific (2Eh)
The Erase Block Tag Specific command is used for Tag specific block erases. The
format for this command is as follows:
Currently, the only acceptable Chip Type is 0x00 (indicates standard support of any tag
supporting the Block Erase command as specified in the Gen2 Specification) and the only
permissible option is 00 (Block Erase). The 32-bit Address field is the zero-based offset
from the MemBank origin, in 16-bit words, where the contents of the tag memory will be
erased. 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 mentioned for
Write Tag Data command. Word Count specifies the number of 16-bit words to be
erased. In the format example, data starting at word=0x02 (the third word) of EPC
memory, which corresponds with the first word of the EPC ID, is erased .
