Nordic FLL16M
|
|
|
|
The FLL16M can use the following clocks as clock sources:
|
|
|
|
- HFXO: The HFXO clock is used as a clock source if the
|
|
FLL16M mode is BYPASS, or if the FLL16M mode is
|
|
closed-loop and the LFXO clock is not available.
|
|
|
|
- LFXO: The LFXO clock is used as a clock source if the
|
|
FLL16M mode is closed-loop and the LFXO clock is
|
|
available.
|
|
|
|
Devicetree example:
|
|
|
|
fll16m {
|
|
open-loop-accuracy-ppm = <20000>;
|
|
closed-loop-base-accuracy-ppm = <5000>;
|
|
clocks = <&hfxo>, <&lfxo>;
|
|
clock-names = "hfxo", "lfxo";
|
|
};

Base clock accuracy in parts per million if closed-loop clock source is used.

The actual accuracy is this property plus the accuracy of the HFXO or LFXO.
