notSupported(0). The interface does not support control of
transmitter on fault. This value can only be read, and can
never be written.
enable(1). Will turn off (mute) transmitter power on fault.
disable(2). Will output default signal on fault.

intended to be used with through timing mode. In aligned
mode, output is always freezed anyway regardless if this
value is set or not. Valid if `fs' bit is set in
itsIfCapabilities.
