8.5.2 L3 CONTROL MODE
The L3 control mode allows maximum flexibility in controlling the UDA1350ATS.
It should be noted that in the L3 control mode several base-line functions are still controlled by pins on the device and
that on start-up in the L3 control mode the output is explicitly muted by bit MT via the L3 interface.
