FUNCTION
POR
The power supply for the digital part of the device, V
DDD2
, has temporarily been
lower than the specified lower limit. If this is detected an initialization of the
TDA9870A has to be carried out to ensure reliable operation.
this bit is HIGH if an FM stereo signal has been identified
This bit is HIGH 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.
these bits reflect the status of the corresponding general purpose port pins,
