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

Must be set to ‘OFF’ in case of dual carrier stereo (Ger-
man or Korean). If ‘ON’, FM fixed deemphasis must be
set to 75 µs.
RESET: The RESET state is taken 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 rede-
fined.
