When LNMP bit is “1”, MPE pin becomes LIN pin. When RNMD bit is “1”, MDT pin becomes RIN pin. LIN/RIN is
single-ended input. The AK4650 has a volume for Stereo Line Input. This Volume is controlled by GL4-0 and GR4-0 bits
as shown in Table 28. The switching noise occurs when GL4-0 or GR4-0 bits are changed.
