6 FROM_LINE_R If set, the RIGHT_MIC/LINE differential input is routed to the AUX_R input amplifier for line level volume

control. This bit overrides the DIFF_MODE (bit 7) setting.

7 DIFF_MODE If set, the stereo single-ended inputs AUX_L and AUX_R convert to a mono differential input pair MONO_IN+

and MONO_IN-.

(MONO_IN+) - (MONO_IN-) is routed to the AUX_L input amplifier.

(MONO_IN-) - (MONO_IN+) is routed to the AUX_R input amplifier.

(unless overriden by the respective FROM_LINE bits).
