Default
Initial value is “01” (OFF).
Initial value is “00” (Normal speed).
When changing between Normal/Double Speed Mode and Quad Speed Mode, some click noise occurs at
that time.
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 go to “H” only when the input data at both
channels are continuously zeros for 8192 LRCK cycles.
