Rch出力選択。自動音声出力選択(AUTO bit)がディセーブル時は、Rch出力をRSEL[1:0]bitで選択します。
自動音声出力選択(AUTO bit)がイネーブル時もRSEL[1:0]bit はTable 70に示すように音声選択方法を決定
します。

Left / Right Outputs
Standard Mode
Left and right outputs are unchanged.
Summing Mode
L = R = (LStndrd + RStndrd) / 2
LStndrd and RStndrd are defined as what the left and right
outputs would be if LRSM were 0(inactive)
