L3
CONTROL MODE
The L3 control mode allows maximum flexibility in controlling the UDA1351H.
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.
Also it should be noted that in using the L3 control mode, an initialization string is needed after power-up of the device
for reliable operation.
