How does pin 5 or 9 works? Even disable DVK or BandData ?
Pin 5 is used to drive external DVK, and pin 9 is used for BandData.
Both function are not compatible with stereo switch, even you can set
DVK+Stereo or DVK+BandData
BandData+Stereo or BandData+DVK
There are also some limitation with some hardware that don't support pin2
DVK Stop pulse and Pin2 as one bit of the BandData nibble. In this last
BandData+Stereo(pin5) or DVK+Stereo(pin9)
is the only one choice.
