DATA BYTE
Keyed FM AGC. If KAGC = 0, then keyed FM AGC is off. If KAGC = 1, then keyed
FM AGC is on.
Wide band AGC. These 2 bits set the start value of wide band 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.
In test mode charge pump 3-state. If TMS3 = 0, then 3-state off. If TMS3 = 1, then
3-state on.
In test mode external clock for level and antenna DAA. If TMS2 = 0, then external
clock disabled. If TMS2 = 1, then external clock enabled.
In test mode setting of pin f
see Table 19.
