(3) Mode switch (L-, R-channel output (LOT, ROT pins))
The signal to be output can be selected from the L- and R-channel outputs (LOT, ROT pins) with bits D3 to D1
of subaddress 06H. For the combinations of bit and output signal, refer to section
5.1 L-, R-Channel Output
(LOT, ROT pins) Matrix
.
Forced monaural ON/OFF : When set to ON, a monaural signal is forcibly output regardless of the selection
of other bits.
Stereo/SAP switch
: When forced monaural is set to OFF, performs selection of stereo or SAP.
