1: Dependent (default)
When OVOLC bit = “1”, OVL7-0 bits control both Lch and Rch volume level, 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.
OVTM: Digital Volume Transition Time Setting
0: 1061/fs (default)
1: 256/fs
This is the transition time between OVL/R7-0 bits = 00H and FFH.
SMUTE: Soft Mute Control
0: Normal Operation (default)
1: DAC outputs soft-muted
