DEM1-0: De-emphasis Filter Frequency Select (Table 9)
Default: “01” (OFF)
BST1-0: Low Frequency Boost Function Select (Table 10)
Default: “00” (OFF)
SMUTE: Soft Mute Control
0: Normal operation (Default)
1: DAC outputs soft-muted
LMUTE: Mute control for LOUT/ROUT (Note 19)
0: Normal operation. ATTS3-0 bits control attenuation value.
1: Mute. ATTS3-0 bits are ignored. (Default)
DATTC: DAC Digital Attenuator Control Mode Select
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.
ATS: Digital attenuator transition time setting (Table 8)
0: 1061/fs (Default)
