Event Interrupt mode is drawn as if the user is reading the part. If the user doesn't read, the outputs would go low and
stay that way until the LM76 is read.

TEMPERATURE DATA FORMAT
Temperature data can be read from the Temperature and Set Point registers; and written to the Set Point
registers. Temperature data can be read at any time, although reading faster than the conversion time of the
LM76 will prevent data from being updated. Temperature data is represented by a 13-bit, two's complement word
with an LSB (Least Significant Bit) equal to 0.0625°C:
