AK4628A: CODEC (IC401: X08) Port Descriptions
Port No. Port Name I/O Explanations Logic
1 SODS I
SDTO Source Select port.
SDOS port should be set to “L” when TDM-“1”
L: Internal ADC output,
H: DAUX input.
2 I2C I Control Mode Selection port. L: 3-Bus Serial, H: I2C Bus.
3 SMUTE I Soft Mute port.
When this port goes to “H”, soft mute cycle is initialized.
When returning to “L”, the output mute releases.
4 BICK I Audio Serial Data Clock port. -
