Reset Function
When the MCLK or LRCK stops, the AK4420 is placed in reset mode and its analog outputs are set to VSS (0V, typ).
When the MCLK and LRCK are restarted, the AK4420 returns to normal operation mode. The BICK can be stopped
when MCLK or LRCK is stopped, but it must not be stopped when MCLK and LRCK are supplied.

Notes:
(1)
Digital data can be stopped. The click noise after MCLK and LRCK are input again can be reduced by inputting
the “0” data during this period.
(2)
The analog output corresponding to a specific digital input has group delay (GD).
(3)
No audible click noise occurs under normal conditions.
(4)
Clocks (MCLK, BICK, LRCK) can be stopped in the reset mode (MCLK or LRCK is stopped).
(5)
The AK4420 detects the stop of LRCK if LRCK stops for more than 2048/fs. When LRCK is stopped, the
AK4420 exits reset mode after LRCK is inputted..
(6)
The DZF pin is set to “L” in the reset mode.
