LST[4:0]
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.

SWPORT2
Software programmable port 2.
If SWPORT2 = 0, then pin SWPORT2 is inactive
(high-impedance). If SWPORT2 = 1, then pin SWPORT2 is active (pull down to ground).
Software programmable port 1.
If SWPORT1 = 0, then pin SWPORT1 is inactive
(high-impedance). If SWPORT1 = 1, then pin SWPORT1 is active (pull down to ground).
AM noise blanker.
If AMNB = 0, then the AM noise blanker is off. If AMNB = 1, then the
AM noise blanker is on.
These 5 bits are not used and should be set to logic 0.
