Note: The DATA_SEL[1:0] bits in reg09h must be set to ‘01’b to enable function control in this register.

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.
Limiter Release Rate Register (Address 1Ah)
Peak Detect and Limiter Enable (LIMIT_EN)
Default: 0
0 - Disabled
1 - Enabled
Function:
Limits the maximum signal amplitude to prevent clipping when this function is enabled. Peak Signal Limiting
is performed by digital attenuation. Note: When the limiter is enabled, the AOUT Volume is automatically
controlled and should not be adjusted manually. Alternative volume control may be realized using the
PCMMIXx_VOL[6:0] bits.
Peak Signal Limit All Channels (LIMIT_ALL)
Default: 1
0 - Individual Channel
1 - Both channel A & B
Function:
When set to 0, the peak signal limiter will limit the maximum signal amplitude to prevent clipping on the spe-
cific channel indicating clipping. The other channels will not be affected.
When set to 1, the peak signal limiter will limit the maximum signal amplitude to prevent clipping on both
channels in response to any single channel indicating clipping.
