LPAE: Gain Adjustment for Bass Boost Gain Control
Default value: 0
A gain setting for bass boost may cause digital data may saturation, depending on the input data level. Where
this could occur, LPAE can be used to set the same attenuation level as the bass boost gain level for the digital
input data.
LPAE = 0
Disable (default)
LPAE = 1

LGA[4:0]: Bass Boost Gain Control
Default value: 0 0000
These bits are used to set the bass boost gain level for digital data. The detailed characteristic is shown in the
Typical Performance Curves.
