I2S: Audio Format
“0”: MSB justified
“1”: I2S
512FS: Master Clock Output Frequency
“0”: 256fs
“1”: 512fs
SDIN: Ext. Audio Input Interface Enable
“0”: Power-down and Disable: SDTI pin must be connected to VSS1-3.
“1”: Power-up and Enable
If this bit is set to “1”, the AK5373 receives audio data via the external digital audio interface and transmits
them to the host instead of the A/D data generated by the AK5373.
SDOUT: Ext. Audio Output Interface Enable
“0”: Power-down and Disable: SDTO pin = “L”
“1”: Power-up and Enable
If this bit is set to “1”, the A/D data is output via this Interface.

STEREO: Mono/Stereo Mode Select
“0”: Mono
“1”: Stereo
SIGNED: Unsigned/Signed Mode Select
“0”: Unsigned (“0” is valid only when the resolution is 8 bit)
“1”: Signed
RES1-0: ADC Resolution Mode Select
“00”: 8bit
“01”: 16bit
“10”: 24bit
MIX: ADC Data Mix Control
“0”: Lch and Rch are not mixed.
“1”: Lch and Rch are mixed. Dynamic range and S/N can be improved by approximately 3dB when the same analog
signal is inputted to left and right channels.
