enhanced buffered write words (EW)
Command:
Response:
The read/write head repeatedly attempts to write <WordNum> 32-bit words from
the address <WordAddr> until successful. After each successful write, the head
sends the response and then switches to continuous read. The read/write head
then reads the same tag until the tag has left the detection range or a new tag
appears within the detection range. At this point, the read/write head again starts
write attempts.
The status '05h' is only output when a tag leaves the detection range or is not yet
within the detection range.
