4*6c6a6ee9SJonathan CameronDescription:
5*6c6a6ee9SJonathan Cameron		Overvoltage or Undervoltage Input Fault. The internal circuitry
6*6c6a6ee9SJonathan Cameron		is protected from excessive voltages applied to the thermocouple
7*6c6a6ee9SJonathan Cameron		cables. The device can also detect if such a condition occurs.
8*6c6a6ee9SJonathan Cameron
9*6c6a6ee9SJonathan Cameron		Reading returns '1' if input voltage is negative or greater
10*6c6a6ee9SJonathan Cameron		than VDD, otherwise '0'.

15*6c6a6ee9SJonathan CameronDescription:
16*6c6a6ee9SJonathan Cameron		Open-circuit fault. The detection of open-circuit faults,
17*6c6a6ee9SJonathan Cameron		such as those caused by broken thermocouple wires.
18*6c6a6ee9SJonathan Cameron		Reading returns '1' if fault, '0' otherwise.
