Reset Function
When RSTN=0, DAC is powered down but the internal register values are not initialized. The analog outputs go to VCOM
voltage and DZF pin goes to “H”. Figure 7 shows the example of reset by RSTN bit.

Notes:
(1) The analog output corresponding to digital input has the group delay (GD).
(2) Analog outputs go to VCOM voltage (VDD/2).
(3) Click noise occurs at the edges(“

”) of the internal timing of RSTN bit. This noise is output even if “0” data is
input.
(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
internal RSTN “1”.
