Temperature data format
Table 3
Temperature data for the temperature, T
two’s complement word.
The left-most bit in the output data stream contains temperature polarity information for
each conversion. If the sign bit is '0', the temperature is positive and if the sign bit is '1,' the
temperature is negative.
Table 3.
Bus timeout feature
The STLM75 supports an SMBus compatible timeout function which will reset the serial
I
between a START and STOP condition. If this occurs, the device will release the bus and
wait for another START condition.
