a. The controlling microprocessor generates 16 clock pulses for output of 16 bits of buffered
b. The controlling microprocessor generates 20 clock pulses for output of 16 bits of buffered
RDS data. This mode use is compatible with e.g. SAA770xH and TEF6890H.
RDS data, a separator bit (logic 1) and 3 bits of RDQ bit quality counter information.
RDQ: 111 = good reception, 000 = poor or no reception. RDQ counter decrements on
each bad quality data bit.
