*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.
