 transponder. If the address flag is set, the

address forms the first part of the data section, followed by a single byte containing the
number of the block to lock.

Reads blocks of data from a Tag-it

TM

 transponder. The address flag should not be

used. The data section contains a single byte detailing the blocks to be read. Each bit
of this byte represents a block of data (bit 0 = block 0 etc) if a bit is set then that block
is read. If the data byte is zero then only the SID is returned. The SID is always
retrieved first and then used to read the selected blocks in addressed mode.
