NO_MATRIX is used for terrestrial mono or satellite ste-
reo sound. GSTEREO dematrixes [(L+R)/2, R] to [L, R]
and is used for German dual carrier stereo system
(Standard B/G). KSTEREO dematrixes [(L+R)/2,
(L–R)/2] to [L, R] and is used for the Korean dual carrier
stereo system (Standard M).

* = RESET position, which becomes active at the
time of the first write transmission on the control
bus to the audio processing part (DSP). By writing
to the ACB register first, the RESET state can be
redefined.
Note: After RESET, SC1_OUT_L/R is undefined!
Note: If “MONO_IN” is selected at the DSP_IN selec-
tion, the channel matrix mode of the corresponding out-
put channel(s) must be set to “sound A”.
