RSTN: Internal timing reset
0: Reset. All DZF pins go to “H” and any registers are not initialized.
1: Normal operation
When MCLK frequency or DFS changes, the AK4358 should be reset by PDN pin or RSTN bit.
DIF2-0: Audio data interface modes (See Table 10, Table 11, Table 12, PCM Only)
Initial: “010”
Register bit of DIF0 is ORed with the DIF0 pin.
DZFE: Data Zero Detect Enable
0: Disable
1: Enable
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”.
SLOW: Slow Roll-off Filter Enable (PCM Only)
0: Sharp Roll-off Filter
1: Slow Roll-off Filter
ACKS: Master Clock Frequency Auto Setting Mode Enable
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.
