NOTE

Whenever changing between standard and extended temperature ranges, be aware that

the temperatures stored in the temperature limit registers are NOT automatically

reformatted to correspond to the new temperature range format. These temperature limit

values must be reprogrammed in the appropriate binary or extended binary format.

Both local and remote temperature data use two bytes for data storage. The high byte stores the temperature

with 1°C resolution. The second or low byte stores the decimal fraction value of the temperature and allows a

higher measurement resolution; see Table 3. The measurement resolution for the remote channel is 0.0625°C,

and is not adjustable. The measurement resolution for the local channel is adjustable; it can be set for 0.5°C,

0.25°C, 0.125°C, or 0.0625°C by setting the RES1 and RES0 bits of the Resolution Register; see the Resolution

Register section.
