DTSC_Enable VDSC_Enable
Soft_clip control register is used to enable the soft clipping function. There are two bits in this register to control two soft clip blocks
independently.
VDSC_Enable
When set, enable soft clip function for network signal before network signal is sent to AEC module.
When reset, disable soft clip function. So network signal is sent to AEC module directly.
DTSC_Enable
When set, enable soft clip function for acoustic signal after acoustic signal is sent out from AEC module.
When reset, disable soft clip function. So acoustic signal is sent to next stage directly.
