Configuration, Command, and Status Registers
SOE (Strobe Oscillator Enable) enables the strobe oscillator.
Figure 21
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
OLA[1:0] (Output Level Attenuation) define the RF output level attenuation.
AFF[1:0] (Average Filter Frequency) define the average filter cut-off frequency if the AFFC bit is set.

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
