Used for factory trimming of the baseband filters.
1 = disables the quadrature mixers for filter tuning
0 = enables the quadrature mixers
Control diagnostic features as follows:
000 = normal operation
001 = force charge-pump source current
010 = force charge-pump sink current
011 = force charge-pump high-impedance state
100 = power-detector RMS voltage at PWRDET
101 = N-divider output at TEST pin
110 = R-divider output at TEST pin
111 = local oscillator output at TEST pin
Set the charge-pump current.
00 = ±1.5mA
01 = ±2mA
10 = ±2.5mA
11 = ±3mA
Sets the charge-pump current selection mode between automatic and manual.
0 = charge-pump current is set manually through the CP[1:0] bits
1 = charge-pump current is automatically selected based on ADC read values
in both VAS and manual VCO selection modes
Controls the charge-pump prebias function.
0 = disables the charge-pump prebias function
1 = enables the charge-pump prebias function
Sets the prebias on-time control from reference divider.
0 = 280ns
1 = 650ns
Sets the prebias on-time control from VCO/LO divider.
0 = 500ns
1 = 1000ns
Sets the charge-pump on-time control.
0 = 2.5ns
1 = 5ns
Controls the VCO autoselect (VAS) function.
0 = disables the VCO autoselect function and allows manual VCO selection
through the VCO[1:0] and VSB[2:0] bits
1 = enables the on-chip VCO autoselect state machine
