When RSTN = ”0”, the AK4395’s digital section is powered down but the internal register values are not initialized. The
analog outputs go to VCOM voltage and DZF pins of both channels go to “H”. Figure 7 shows the example of reset by
RSTN bit.

MS0040-E-01
Reset Function
(1) The analog output corresponding to digital input has the group delay (GD).
(2) Analog outputs go to VCOM voltage.
(3) Click noise occurs at the edges(“
(4) The external clocks (MCLK, BICK and LRCK) can be stopped in the reset mode (RSTN = “L”).
(5) DZF pins go to “H” when the RSTN bit becomes “0”, and go to “L” at 2/fs after RSTN bit becomes “1”.
(6) There is a delay, 3~4/fs from RSTN bit “0” to the internal RSTN bit “0”, and 2~3/fs from RSTN bit “1” to the
