SDETR1
Interpolator silence detect channel 1 right.
When this bit is logic 0:
interpolator on channel 1 right input has detected no silence. When this bit is
logic 1: interpolator on channel 1 right input has detected silence.
Interpolator silence detect channel 1 left.
When this bit is logic 0:
interpolator on channel 1 left input has detected no silence. When this bit is
logic 1: interpolator on channel 1 left input has detected silence.
Interpolator muting.
A 1-bit value which signals whether the interpolator has
reached mute or not. When this bit is logic 0: interpolator is not muted. When
this bit is logic 1: interpolator is muted.
Interpolator muting channel 2.
When this bit is logic 0: interpolator channel 2
is not muted. When this bit is logic 1: interpolator channel 2 is muted.
Interpolator muting channel 1.
When this bit is logic 0: interpolator channel 1
is not muted. When this bit is logic 1: interpolator channel 1 is muted.

AGC_STAT
not used
AGC gain status.
A 1-bit value which signals whether the AGC gain exceeds
8 dB or not. Only valid when the AGC is switched on. When this bit is logic 0:
AGC gain <8 dB. When this bit is logic 1: AGC gain
≥
8 dB.
not used
Decimator mute.
A 1-bit value which signals whether the decimator has
reached mute or not. When this bit is logic 0: decimator has not muted. When
this bit is logic 1: decimator has muted.
not used
Digital output overflow detection.
A 1-bit value which signals whether the
digital output amplitude exceeds
1.16 dB or not. When this bit is logic 0: no
overflow detected (read-out). When this bit is logic 1: overflow detected
(read-out).
