1.5 TEMPERATURE DATA FORMAT
Temperature data is represented by a 13- to 16-bit, two's
complement word with a Least Significant Bit (LSB) equal to
13-Bit Resolution. First Bit (D15) is Sign, the last bit (D0) is Toggle and bits D1 and D2 are always 0.
14-Bit Resolution. First bit (D15) is Sign, the last bit (D0) is Toggle and bit D1 is always 0.
