Register Definitions
Addr
Register Name
00H
Control 1
default
RSTN: Internal timing reset control
0: Reset. All registers are not initialized.
1: Normal Operation
When MCLK frequency or DFS changes, the AK4384 should be reset by PDN pin or RSTN bit.
PW: Power down control
0: Power down. All registers are not initialized.
1: Normal Operation
DIF2-0: Audio data interface formats (see Table 7)
Initial: “010”, Mode 2
ACKS: Master Clock Frequency Auto Setting Mode Enable
0: Disable, Manual Setting Mode
1: Enable, Auto Setting Mode
Master clock frequency is detected automatically at ACKS bit “1”. In this case, the setting of DFS1-0
are ignored. When this bit is “0”, DFS1-0 set the sampling speed mode.

DEM1-0: De-emphasis Response (see Table 9)
Initial: “01”, OFF
DFS1-0: Sampling speed control
00: Normal speed
01: Double speed
10: Quad speed
When changing between Normal/Double Speed Mode and Quad Speed Mode, some click noise occurs.
SLOW: Slow Roll-off Filter Enable
0: Sharp Roll-off Filter
1: Slow Roll-off Filter
DZFE: Data Zero Detect Enable
0: Disable
1: Enable
Zero detect function can be disabled by DZFE bit “0”. In this case, the DZF pins of both channels are
always “L”.
