+Description
+-----------
+
+The LM77 implements one temperature sensor. The temperature
+sensor incorporates a band-gap type temperature sensor,
+10-bit ADC, and a digital comparator with user-programmable upper
+and lower limit values.
+
+Limits can be set through the Overtemperature Shutdown register and
+Hysteresis register.
