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.
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.
IF counter result. These bits contain the least significant eight bits of the IF counter
result.
