 4Description:
 5		Overvoltage or Undervoltage Input Fault. The internal circuitry
 6		is protected from excessive voltages applied to the thermocouple
 7		cables. The device can also detect if such a condition occurs.
 8
 9		Reading returns '1' if input voltage is negative or greater
10		than VDD, otherwise '0'.
