8.7.8
8.7.8.1
By writing to the 7FH register, all L3 control values are
restored to their default values. Only the L3 interface is
affected, the system will not be reset. Consequently
readable registers, which are not reset, can be affected.
8.7.8.2
A 1-bit value to switch the DAC on and off.
Table 10 Power-on setting
8.7.8.3
A 1-bit value to select an IEC 958 input channel.
Table 11 Slicer input selection
8.7.8.4
A 1-bit value to select the source for clock regeneration,
either from the IEC 958 input or digital data input interface.
In the event that the IEC 958 input is used as a clock
source the UDA1351H is clock master on the digital data
output and input interfaces.
Table 12 Clock source selection
8.7.8.5
A 1-bit value to select the data source, either the IEC 958
input or the digital data input interface.

A 2-bit value to set the serial format for the digital data
output and input interfaces.

8.7.8.7
A 2-bit value to program the mode for the sound
processing filters of bass boost and treble.

8.7.8.8
A 2-bit value to program the treble setting in combination
with the filter mode settings. At f
point for minimum setting is 3.0 kHz and the 3 dB point
for maximum setting is 1.5 kHz. The default value is ‘00’.
