Auto-select function: for TV applications, only in combination with bit IDSWFM = 1. If set
to logic 1, it switches the matrix automatically depending on bits IDSTE and IDDUA for
FM and the bits S/MB, D/SB for NICAM (see Sections 7.4.1 and 7.4.2).
Output channel selection mode, stereo output: these bits select the output channel
selection mode; see Table 51
Signal source for mono output: these bits select the signal source for the mono output;
see Table 52
Signal source for stereo output: these bits select the signal source for the stereo output;
see Table 53
