    - Reading gives the state of AC excitation.
    - Writing '1' enables AC excitation.
    + This attribute, if available, is used to enable the AC
    + excitation mode found on some converters. In ac excitation mode,
    + the polarity of the excitation voltage is reversed on
    + alternate cycles, to eliminate DC errors.
