Programs the bandwidth of the baseband filter. Optimum values for 6MHz to 8MHz wide
channels can be calculated after reading a ROM table entry. See the Reading the ROM
Table section.
Baseband filter bias current control:
1 = High-bias current.
0 = Low-bias current.
Programs the power-detector attack point for closed-loop RF gain control; see the
Typical Operating Characteristics for power-detector behavior:
000 = Most aggressive RF gain reduction.

Controls which VCO is activated when using manual VCO programming mode:
00 = VCO disabled.
01 = Select VCO 0 (lowest frequency VCO).
10 = Select VCO 1.
11 = Select VCO 2 (highest frequency VCO).

100 = Select sub-band 4.
101 = Select sub-band 5.
110 = Select sub-band 6.
111 = Select sub-band 7 (highest frequency sub-band).
Enables or disables the VCO autotuner function:
1 = VCO and VCO sub-band are programmed automatically by the autotuner.
0 = VCO and VCO sub-band selection is controlled manually by programming the
VCO[1:0] and SB[2:0] bits.
Enables or disables the VCO tuning voltage ADC latch when the VCO autotuner is
disabled (VAS = 0):
1 = Latches the ADC output.
0 = Disables the ADC latch.
Enables or disables the VCO tuning voltage ADC read when the VCO autotuner is
disabled (VAS = 0):
1 = Enables ADC read.
0 = Disables ADC read.
