*DATA_VALID is set when a new result is written into the register.
DATA_VALID is cleared when this register is addressed (read) by the I

C
interface.
**Sensor Short is high if the voltage measured on V1 is too low
during temperature measurements. This signal is always low for T
INT
measurements.
†
Sensor Open is high if the voltage measured on V1 is excessive
during temperature measurements. This signal is always low for T
INT
measurements.
