Default
SMUTE: Soft Mute Enable
0: Normal Operation (default)
1: DAC outputs soft-muted.
DEM1-0: De-emphasis Response (Table 12)
Initial value is “01” (OFF).
DFS1-0: Sampling Speed Control (Table 6)
Initial value is “00” (Normal speed).
When changing between Normal/Double Speed Mode and Quad Speed Mode, some click noise occurs at
that time.
SLOW: Slow Roll-off Filter Enable
0: Sharp roll-off filter (default)
1: Slow roll-off filter
DZFM: Data Zero Detect Mode
0: Channel Separated Mode (default)
1: Channel ANDed Mode
If the DZFM bit is set to “1”, the DZF pins of both channels go to “H” only when the input data at both
channels are continuously zeros for 8192 LRCK cycles.
DZFE: Data Zero Detect Enable
0: Disable (default)
1: Enable
Zero detect function can be disabled by DZFE bit “0”. In this case, the DZF pins of both channels are
always “L”.
