Auto-select function: for TV applications, only in combination with IDSWFM set HIGH.
If set HIGH switches the matrix automatically depending on the IDSTE, IDDUA bits for
FM and the S/MB, D/SB bits for NICAM (see Sections 10.4.1 and 10.4.2).
Output channel selection mode, stereo output: these 3 bits select the output
channel selection mode; see Table 53
Signal source for mono output: these 2 bits select the signal source for the mono
output; see Table 54
Signal source for stereo output: these 2 bits select the signal source for the stereo
output; see Table 55
