DEM1-0: De-emphasis Control (Table 39)
Default: “01” (OFF)
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.
OVOLC: Output Digital Volume Control Mode Select
0: Independent
1: Dependent (default)
When OVOLC bit = “1”, OVL7-0 bits control both Lch and Rch volume levels, while register values of
OVL7-0 bits are not written to OVR7-0 bits. When OVOLC bit = “0”, OVL7-0 bits control Lch level and
OVR7-0 bits control Rch level, respectively.
DVOLC: Output Digital Volume2 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
0: Normal Operation (default)
1: DAC outputs soft-muted
THDET: Thermal Shutdown Detection
0: Thermal Shutdown Off (default)
1: Thermal Shutdown On
READ: Read Function Enable
