Reset pulse.
Presence pulse.
Skip ROM command.
Write Scratchpad command.
Writes three bytes to scratchpad (TH, TL, and config).
Reset pulse.
Presence pulse.
Skip ROM command.
Read Scratchpad command.
Read entire scratchpad plus CRC. The master now
recalculates the CRC of the eight data bytes received
from the scratchpad, compares the CRC and the two
other bytes read back from the scratchpad. If data match,
the master continues; if not, repeat the sequence.
Reset pulse.
Presence pulse.
Skip ROM command.
Copy Scratchpad command; after issuing this command,
the master must wait 10 ms for copy operation to
complete.
Reset pulse.
Presence pulse, done.
