This bit is logic 1 if an FM dual-language signal has been identified. When
neither IDSTE nor IDDUA are set, the received signal has to be assumed to be
FM mono.
This bit is logic 1 if an FM stereo signal has been identified.
Power fail bit: the power supply for the digital part of the device, V
temporarily been lower than the specified lower limit. If this is detected an
initialization of the TDA9870A has to be carried out to ensure a reliable
operation.
