8.6
The UDA1351H can be controlled by means of static pins or via the L3 interface. For optimum use of the features of the
UDA1351H the L3 control mode is recommended since only basic functions are available in the static pin control mode.
It should be noted that the static pin control mode and L3 control mode are mutual exclusive. In the static pin control
mode pins L3MODE and L3DATA are used to select the format for the data output and input interface.
8.6.1
The default values for all non-pin controlled settings are identical to the default values at start-up in the L3 control mode.
