EXAMPLE:
Writes 4 bytes of data, starting at address 0001H. A timeout of 2 seconds
(07D0H = 2000 x 1 msec increments) is set for the completion of the Block
Write. The Family ID byte is set to 2, so all tags with Family ID of 2 will be
written to (four tags in this example). The Anticollision Index is set to 2, so
4 to 8 tags are expected in the field.
