Cushion Threshold (CUSH[2:0])
Default: 000
Function:
Sets a cushion level below full scale. This setting is usually set slightly below the maximum (MAX[2:0])
threshold. The Limiter uses this cushion as a hysteresis point for the input signal as it maintains the signal
below the maximum as well as below the cushion setting. This provides a more natural sound as the limiter
attacks and releases.
Limiter Soft Ramp Disable (LIM_SRDIS)
Default: 0
0 - Off
1 - On
Function:
Overrides the DAC_SZC setting. When this bit is set, the Limiter attack and release rate will not be dictated
by the soft ramp setting. Note: This bit is ignored when the zero-cross function is enabled (i.e. when
DAC_SZC[1:0] = ‘01’b or ‘11’b.)
Limiter Zero Cross Disable (LIM_ZCDIS)
Default: 0
0 - Off
1 - On
Function:
Overrides the DAC_SZC setting. When this bit is set, the Limiter attack and release rate will not be dictated
by the zero-cross setting.
