Mode
00: Normal speed
01: Double speed
10: Quad speed
When changing between Normal/Double Speed Mode and Quad Speed Mode, some click noise occurs.
All sections are powered-down by PW1=PW2=PW3=PW4=0.
PW1: Power down control of DAC1
This bit is duplicated into D1 of 00H.
PW2: Power down control of DAC2
PW3: Power down control of DAC3
PW4: Power down control of DAC4
Default
0: DZF goes “H” at Zero Detection
1: DZF goes “L” at Zero Detection
0: Disable, Manual Setting Mode
1: Enable, Auto Setting Mode
Master clock frequency is detected automatically at ACKS bit “1”. In this case, the setting of DFS1-0
bits are ignored. When this bit is “0”, DFS1-0 bits set the sampling speed mode.
0: Normal operation
1: DAC outputs soft-muted
Initial: “01”, OFF
0: Sharp Roll-off Filter
1: Slow Roll-off Filter
