COMMENTS
Reset pulse (480-960 μs).
Presence pulse.
Issue “Match ROM” command.
Issue address for DS18S20.
Issue “ Convert T” command.
I/O line is held high for at least 750 ms by bus master to
allow conversion to complete.
Reset pulse.
Presence pulse.
Issue “Match ROM” command.
Issue address for DS18S20.
Issue “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 calculated and
the CRC read. If they match, the master continues; if
not, this read operation is repeated.
Reset pulse.
Presence pulse, done.
