Sets the low-frequency clock divider.
00 = Use for 16MHz P f
01 = Use for 20MHz P f
10 = Use for 28MHz P f
11 = Unused
Controls the VCO autoselect (VAS) start conditions function.
0 = VAS starts from the current VCO/VCOSB loaded in the VCO[1:0] and VSUB[3:0]
bits (in R00)
1 = VAS starts from the currently used VCO and VCOSB
Controls the VCO autoselect (VAS) function. Must set to 1 for proper operation.
Enables or disables the VCO tuning voltage ADC latch when the VCO autoselect
(VAS) mode is disabled.
0 = Disables the ADC latch
1 = Latches the ADC value
Enables or disables VCO tuning voltage ADC read when the VCO autoselect (VAS)
mode is disabled.
0 = Disables ADC read
1 = Enables ADC read
Sets the VCO autoselect wait time. Must set to 10 for proper operation.
Enables or disables wideband power detector.
0 = Enables wideband power detector. Use this state for autonomous RFAGC.
1 = Disables wideband power detector
Sets the wideband power-detector attack point (takeover point).
000 = Min
100 = Nom (see the Typical Operating Characteristics)
111 = Max
Enables or disables narrowband power detector.
0 = Enables narrowband detector. Use this state for autonomous RFAGC.
1 = Disables narrowband detector
Sets the narrowband power-detector attack point (takeover point).
