DIFFERENTIAL MONO LINE-IN
The WM8955BL can take either a single-ended or a differential mono signal and mix it into the
LOUT1/2 and ROUT1/2 outputs. In both cases, LINEINL and LINEINR still remain available as stereo
line-in. Differential mono input mode is enabled by setting the DMEN bit, as shown below.
