RSTN: Internal timing reset
0: Reset. DZF pins of all channels go to “H” and registers are not initialized.
1: Normal operation
When the states of SLOW, DIF2-0, CKS2-0 or DFS0-1 changes, the AK4356 should be reset
by PDN pin or RSTN bit. Some click noise occurs at that timing.
DIF2-0: Audio data interface modes (See Table 3.)
Initial: “000”, Mode 0
Register bits of DIF2-0 are ORed with the DFS2-0 pins.
DZFE: Data Zero Detect Enable
0: Disable
1: Enable
Zero detect function can be disabled by DZFE bit. In this case, the DZF pins of all channels
are always “L”. Register bit of DZFE is ORed with the DZFE pin.
DZFM: Data Zero Detect Mode
0: Channel Separated Mode
1: Channel ANDed Mode
If the DZFM bit is set to “1”, the DZF pins of all channels go to “H” only when the input data
at all channels are continuously zeros for 8192 LRCK cycles.
SLOW: Slow roll-off response enable
0: Disable
1: Enable

0: Normal operation
1: All DAC outputs soft-muted
Register bit of SMUTE is ORed with the SMUTE pin.
CKS2-0: Master Clock Frequency Select (See Table 2.)
Initial: “000”, Mode 0
Register bits of CKS2-0 are ORed with the CKS2-0 pins.
