Default
Initial value is “01” (OFF).
The default is “00” (Normal Speed). A click noise occurs when switching DFS1-0 bits.
Zero detect function can be disabled by DZFE bit “0”. In this case, the DZF pins of both channels are
always “L”.
If the DZFM bit is set to “1”, the DZF pins of both channels become “H” only when the input data at both
channels are continuously zeros for 8192 LRCK cycles.
