DACM: DAC Lch and Rch outputs are added to MOUT buffer amp. Summation gain is −6dB for each channel.
LINM: Input signal to LIN pin is added to MOUT buffer amp.
RINM: Input signal to RIN pin is added to MOUT buffer amp.
MINM: Input signal to MIN pin is added to MOUT buffer amp.

Default: MMUTE bit = “0”, ATTM3-0 bits = “0000” (0dB)
Setting of ATTM3-0 bits is enabled at MMUTE bit is “0”.
Gain of summation is 0dB for MIN and −6dB for LIN, RIN, DACL and DACR.
