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.
If two tags enter the read range one immediately after the other, the status '05h' is
not issued between the two readings.
