*2: The conversion speed is a period from when a temperature is input and converted into a corresponding digital value until the value is
stored into the buffer memory.
When two or more channels are used, the conversion speed is "40ms
*3: At wire break detection, the temperature conversion value right before wire break occurrence is held.
