PCM Channel Mixer (Address 18h)
Channel Mixer (PCMx[1:0] & ADCx[1:0])
Default: 00
Function:
Implements mono mixes of the left and right channels as well as a left/right channel swap.
Limiter Threshold SZC Disable (Address 19h)
Maximum Threshold (MAX[2:0])
Default: 000
Function:
Sets the maximum level, below full scale, at which to limit and attenuate the output signal at the attack rate.
Bass, Treble and digital gain settings that boost the signal beyond the maximum threshold may trigger an
attack.
