for 12-bit resolution.
Temperature data for Temperature, T
11-bit, and 12-bit depending upon the resolution bits RC1, RC0 (Bits 6 and 5) in the
Configuration Register (see
The left-most bit in the output data stream controls temperature polarity information for each
conversion. If the Sign Bit is '0', the temperature is positive and of the Sign Bit is '1', the
temperature is negative.
Table 4.
Bus timeout feature
The STTS75 supports an SMSBus 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.
