EXAMPLE:
Reads 2 bytes of data from the tag starting at address 0001H. A timeout of 2
seconds (07D0H = 2000 x 1 msec increments) is set for the completion of
the SN Block Read All. The Family ID byte is set to zero so all tags will be
read. The Anticollision Index is set to 2 so 4-8 tags are expected. Two tags
respond with read data.
