+Description:
+		Open-circuit fault. The detection of open-circuit faults,
+		such as those caused by broken thermocouple wires.
+		Reading returns either '1' or '0'.
+
+		===  =======================================================
+		'1'  An open circuit such as broken thermocouple wires
+		     has been detected.
+		'0'  No open circuit or broken thermocouple wires are detected

+Description:
+		Overvoltage or Undervoltage Input Fault. The internal circuitry
+		is protected from excessive voltages applied to the thermocouple
+		cables by integrated MOSFETs at the T+ and T- inputs, and the
+		BIAS output. These MOSFETs turn off when the input voltage is
+		negative or greater than VDD.
+
+		Reading returns either '1' or '0'.
+
+		===  =======================================================
+		'1'  The input voltage is negative or greater than VDD.
+		'0'  The input voltage is positive and less than VDD (normal
+		     state).
