MEMORY FUNCTION EXAMPLE Table 6
Example: Bus Master writes memory (parasite power and only one DS18B20 assumed).
MASTER MODE
DATA (LSB FIRST)
COMMENTS
TX
Reset
Reset pulse.
RX
Presence
Presence pulse.
TX
CCh
Skip ROM command.
TX
4Eh
Write Scratchpad command.
TX
<3 data bytes>
Writes three bytes to scratchpad (TH, TL, and config).
TX
Reset
Reset pulse.
RX
Presence
Presence pulse.
TX
CCh
Skip ROM command.
TX
BEh
Read Scratchpad command.
RX
<9 data bytes>
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.
TX
Reset
Reset pulse.
RX
Presence
Presence pulse.
TX
CCh
Skip ROM command.
TX
48h
Copy Scratchpad command; after issuing this command,
the master must wait 10 ms for copy operation to
complete.
TX
Reset
Reset pulse.
RX
Presence
Presence pulse, done.
