Please refer to the Input Logic parameters in the DC Electrical
Characteristics table for logic level threshold and compatibility.
When this pin is set HIGH, the device is placed in a power-saving
mode. No data processing occurs, and the digital I/Os are powered
down.
In this mode, the serial digital output signals, SDO and SDO, are
both pulled HIGH.
Serial Audio Output; Channels 3 and 4.
Please refer to the Output Logic parameters in the DC Electrical
Characteristics table for logic level threshold and compatibility.
