Setting of level DAA starting point. These 5 bits determine the offset of the level
detector output voltage.
Setting of level DAA slope. These 3 bits determine the steepness of the level detector
output voltage.
Threshold extension. If TE = 0, then threshold extension is off. If TE = 1, then
threshold extension is on.
Setting of FM IF2 centre frequency DAA. The content of CF6 to CF0 determines the
centre frequency of the 450 kHz filter.
This bit is not used and must be set to logic 0.
FM soft mute. If FMSM = 0, then FM soft mute is off. If FMSM = 1, then FM soft mute is
on.
Setting of FM soft mute slope; 000 is flattest setting; see Fig.8
Setting of soft mute start; 000 is lowest setting; see Fig.9
