Local Temperature data is represented by a 10-bit, two's complement word with an LSb (Least Significant Bit)
equal to 0.25°C. The data format is a left justified 16-bit word available in two 8-bit registers. Unused bits will
always report "0". Local temperature readings greater than +127.875°C are not clamped to +127.875°C, they will
roll-over to negative temperature readings.
