DZFB: Inverting Enable of DZF
- LRCK = fs, BICK = 64fs.
- When AOUT drives some capacitive load, some resistor should be added in series between AOUT and capacitive
- All input pins except pull-down/pull-up pins should not be left floating.

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 cont inuously zeros for 8192 LRCK cycles.
0: DZF goes “H” at Zero Detection
1: DZF goes “L” at Zero Detection
