0: Normal operation. ATTS3-0 bits control attenuation value.
1: Mute. ATTS3-0 bits are ignored. (Default)
0: Independent (Default)
1: Dependent
At DATTC bit = “1”, ATTL7-0 bits control both channel attenuation levels, while register values of
ATTL7-0 bits are not written to the ATTR7-0 bits. At DATTC bit = “0”, the ATTL7-0 bits control the left
channel level and the ATTR7-0 bits control the right channel level.
0: 1061/fs (Default)
1: 7424/fs
0: Normal operation (Default)
1: DAC outputs soft-muted
