nRF LFCLK (Low Frequency CLocK)
|
||
|
|
|
||
|
|
The LFCLK can use the following clocks as clock sources:
|
||
|
|
|
||
|
|
- HFXO: The HFXO clock is used as a clock source if the
|
||
|
|
LFCLK SYNTH mode is selected and the LFXO clock is not
|
||
|
|
available. The HFXO clock is used indirectly through
|
||
|
|
the FLL16M clock in BYPASS mode.
|
||
|
|
|
||
|
|
- LFXO: The LFXO clock is used as a clock source if the
|
||
|
|
LFCLK SYNTH mode is selected and the LFXO clock is
|
||
|
|
available. The LFXO clock is used indirectly through
|
||
|
|
the FLL16M clock in BYPASS mode.
