IVOLC: Input Digital Volume Control Mode Select
0: Independent
1: Dependent (default)
When IVOLC bit = “1”, IVL7-0 bits control both Lch and Rch volume levels, while register values
of IVL7-0 bits are not written to IVR7-0 bits. When IVOLC bit = “0”, IVL7-0 bits control Lch level
and IVR7-0 bits control Rch level, respectively. PMPFIL bit must be “0” when changing the
IVOLC bit setting.
DVOLC: Output Digital Volume Control Mode Select
0: Independent
1: Dependent (default)
When DVOLC bit = “1”, DVL7-0 bits control both Lch and Rch volume levels, while register
values of DVL7-0 bits are not written to DVR7-0 bits. When DVOLC bit = “0”, DVL7-0 bits
control Lch level and DVR7-0 bits control Rch level, respectively.
SMUTE: Soft Mute Control
