Keyed FM AGC. If KAGC = 0, then keyed FM AGC is off. If KAGC = 1, then keyed
FM AGC is on.
Wideband AGC. These 2 bits set the start value of wideband AGC. For AM,
see Table 17 and for FM, see Table 18.
AM soft mute. If AMSM = 0, then AM soft mute is off. If AMSM = 1, then AM soft
mute is on (default).
Local or distance. If LODX = 0, then distance mode is on. If LODX = 1, then local
mode is on.
Software programmable flag. If FLAG = 0, then flag output pin SWFLAG is HIGH.
If FLAG = 1, then flag output pin SWFLAG is LOW.
FM IF2 bandwidth setting. See Table 19.
