The write sequence (downlink mode) of the TK5552 is shown in
data into the transponder occurs by interrupting the RF field with short gaps. After the start gap
the standard op code (11) is followed by the lock bit. The next 32 bits contain the actual data.
The last 5 bits denote the destination block address. If the correct number of bits has been
received, the actual data is programmed into the specified memory block.
