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 AK4381 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.
