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 is
ignored. When this bit is “0”, DFS1-0 set the sampling speed mode.
Register bit of ACKS is ANDed with the inverted of the ACKSN pin.
1: Normal operation
When MCLK frequency or DFS changes, the AK4358 should be reset by PDN pin or RSTN bit.
Initial: “010”
Register bit of DIF0 is ORed with the DIF0 pin.
0: Disable
1: Enable
0: Sharp Roll-off Filter
1: Slow Roll-off Filter
1: Normal operation
When MCLK frequency or DFS changes, the AK4358 should be reset by PDN pin or RSTN bit.
0: Normal operation
1: All DAC outputs soft-muted
0: Reset. All DZF pins go to “H” and any registers are not initialized.
0: Reset. All DZF pins of go to “H” and any registers are not initialized.
Zero detect function can be disabled by DZFE bit “0”. In this case, the DZF pins are “L” at DZFB bit “0”
and are “H” at DZFB bit “1”.
