Function
I2S_PRESCALE
[3:0]
0000
-6 to + 6dB I²S Input prescaling to normalize the incoming audio signal before audio processing.
Auto level control can be implemented by I²C software using the Peak Level Detector.
These bits are used to adjust the corresponding incoming signal level before audio processing.

0: LS/HP/SC/I²S channel unmuted
1: If DEMOD source is selected as OUTPUT channel by CH_SEL and CH_LANG,
then MUTE_LS/MUTE_HP/MUTE_SC signal are set (LS/HP/SC/I²S channel mute)
MUTE_D12
0
0: LS/HP/SC/I²S channel unmuted
1: If DEMOD_1 or DEMOD_2 source is selected as OUTPUT channel by CH_SEL and
CH_LANG, then MUTE_LS/MUTE_HP/MUTE_SC signal are set (LS/HP/SC/I²S
channel mute)
NIC_DMX
0
When 1, Reverse Left/Right Channel to take into account the case where the mono signal would
be carried on the Right Channel.
