When the digital filter is disabled this bit will always read "0".
When the digital filter is enabled this bit will report 1/16°C (0.0625°C) bit state.
When the digital filter is disabled this bit will always read "0".
When the digital filter is enabled this bit will report 1/32°C (0.03125°C) bit state.
Reserved – will report "0" when read.
