Preliminary specification

UDA1351TS

8.5.2 L3 CONTROL MODE

The L3 control mode allows maximum flexibility in controlling the UDA1351TS.

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.
