SOE (Strobe Oscillator Enable) enables the strobe oscillator.
Figure 20
OLS (Out of Lock Status) indicates the current status of the PLL.
LVDS (Low Voltage Detection Status) indicates that a low voltage event has occurred when LVDE = 1.
This bit is read-only and is cleared after a read access.
ILA[1:0] (Input Level Attenuation) define the RF input level attenuation.
Values in
AFF[1:0] (Average Filter Frequency) define the average filter cut-off frequency if the AFFC bit is set.
If AFFC is reset, the average filter frequency is directly defined by bits DR[1:0], as shown in

Reset Value
Bit Name
0 = disabled
1 = enabled
0 = The PLL is in lock-in range
1 = The PLL is out of lock-in range
0 = No low voltage detected
1 = Low voltage detected
