TEMPERATURE DATA FORMAT
Temperature data can only be read from the Local and Remote Temperature registers .
Remote temperature data with the digital filter off is represented by an 11-bit, two's complement word or
unsigned binary word with an LSb (Least Significant Bit) equal to 0.125°C. The data format is a left justified 16-bit
word available in two 8-bit registers. Unused bits will always report "0".

Remote temperature data with the digital filter on is represented by a 13-bit, two's complement word or unsigned
binary word with an LSb (Least Significant Bit) equal to 0.03125°C (1/32°C). The data format is a left justified 16-
bit word available in two 8-bit registers. Unused bits will always report "0".
