Master mute. If this bit is logic 0 then there is no master mute or the master de-mute is in
progress; if this bit is logic 1 then the master mute is in progress or muted.
Gain select. See Table 48.
Mixer gain select. See Tables 48 and 49.
Channel 2 mute. If this bit is logic 0 then channel 2 is not muted or the de-mute is in
progress; if this bit is logic 1 then channel 2 is muted or the muting is in progress.
De-emphasis setting for channel 2. See Table 50.
Interpolator mute. Selection:
WS signal select. If this bit is logic 0 then WS_DET is selected for the WS detection; if
this bit is logic 1 then FPLL is selected for the WS detection.
De-emphasis select. If this bit is logic 0 then SPDIF pre-emphasis information is
selected; if this bit is logic 1 then the de-emphasis setting is selected.
Channel 1 mute. If this bit is logic 0 then channel 1 is not muted or the de-mute is in
progress; if this bit is logic 1 then channel 1 is muted or the muting is in progress.
De-emphasis setting for channel 1. See Table 50.
MTNS0
00 = no mute
01 = if no WS signal is detected, the noise shaper of the interpolator mute
1x = the noise shaper of the interpolator mute
