*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 I2C inteface.

*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 I2C
interface.
**Sensor Short is high if the voltage measured on V1 is too low
during temperature measurements. This signal is always low for TINT
measurements.
†Sensor Open is high if the voltage measured on V1 is excessive
during temperature measurements. This signal is always low for TINT
measurements.
