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.
PW3-1: Power-down control (0: Power-down, 1: Power-up)
PW1: Power down control of DAC1
PW2: Power down control of DAC2
PW3: Power down control of DAC3
All sections are powered-down by PW1=PW2=PW3=0.
DFS1-0:
Sampling speed control (See Table 1.)
00: Normal speed
01: Double speed
10: 4 times speed (DAC2 and DAC3 are automatically powered down.)
Register bit of DFS0 is ORed with the DFS0 pin.
When sampling speed mode is changed between normal and double/4 times speed mode, DFS1-0 bit
should be changed after changing MCLK frequency (figure below). Some click noise occurs at this
timing.

When sampling speed mode is changed between double and 4 times speed mode, sampling mode should
be changed to normal speed mode after changing MCLK frequency, and then it should be changed to
double/4 times speed mode (figure below). Some click noise occurs at those changing timing.
