FOR_MUTE
R/W
When active, the mono sound signal is always muted.
This setting only makes sense in case the sound DAC
output is also set to mono sound
(SSIF_SND[1:0] = 01). FOR_MUTE has no function if
SSIF_SND[1:0] = 10.

AUTO_MUTE
R/W
When active, the mono sound signal is muted if the
horizontal lock flag (N_H_LOCK) disappears. This
setting only makes sense in case the sound DAC
output is also set to mono sound
(SSIF_SND[1:0] = 01). FOR_MUTE has no function if
SSIF_SND[1:0] =10.

mono sound output level
0 0001
12 dB nominal; implemented for flexibility reasons.
With this setting, the adaptation to different standard
requirements can be done.
0 0010
6 dB nominal; implemented for flexibility reasons.
With this setting, the adaptation to different standard
requirements can be done. It is chosen for FM radio
because of the large FM deviation involved.
0 0100
Nominal setting; FM deviations up to 100 kHz can be
processed without sound DAC clipping. The clipping
level is 535 mV (RMS) typically.
0 1000*
+6 dB nominal; chosen for M/N standard due to less
nominal frequency deviation
1 0000
+12 dB nominal; implemented for flexibility reasons.
With this setting, the adaptation to different standard
requirements can be done.
